4 2.2 ODEON - Main functions A)- Automatic connected sensor type and serial number recognition. Calibration coefficients for the parameters measured by the sensor plus former calibration history are stored in the sensor itself and are immediately accessible via the ODEON. The default parameters for each type of sensor are measured and immediately displayed. You then have access to an operational measurement chain. b)- Automatic measurement data refreshing on all selected parameters. c)- Data recording according to three modes : One-shot recording mode: Measurement recording on all active parameters by keyboard command, Automatic regular recording mode : with manual keyboard start-up, Automatic regular recording campaign mode : with campaign beginning and end dates and times. The recorded data are managed in user-named folders (location of measurement campaign, sample name, etc.). d)- Use the RESULT menu to display each measurement recorded in a specific folder, either in cascade mode or by selecting a measurement number. e)- Important for traceability: the operator s identity can be specified. This information will be added to other items, namely in the calibration history. f)- Automatic sleep mode for increased device autonomy. 2.3 Additional device features a)- High level of equipment protection : IP67 watertight warranty when new (not applicable once user has opened the unit, e.g. for battery replacement) b)- Autonomous equipment powered by 4 alkaline AA batteries or 4 AA NiMH accumulators (optional external recharging cable) or by external 12V power supply (optional external power cable). c)- PC connection via USB connector with recorded data recovery and display software. ponsel@ponsel-web.com, wwww.ponsel-web.com 4

7 3.3 Sensor description PODOA : Oxygen/temperature sensor The OPTOD dissolved oxygen sensor operates with optical luminescence measurement technology approved by ASTM International Method D An oxygen-sensitive layer is lit up with a blue LED. The sensitive material emits a red light (Fluorescence). Its intensity and emission time lag vary according to oxygen concentration. This kind of optical technology requires very few consumables : no membrane replacement, no electrolyte. The DO disk containing the sensitive material needs replacing approximately once every 2 years. Technical specifications: Measurement principale Optical luminescence Measurement ranges 0.00 to mg/l or ppm 0-200% SAT Resolution 0.01 Accuracy +/- 0.l mg/l or+/- 1 % Response time (t90) 90% of the value in less than 60 seconds Water movement No circulation required Temperature compensation Via CTN Temperature measurement range 0-60 C Temperature resolution 0.01 Temperature accuracy +/- 0.5 C Storage temperature -10 C to + 60 C Signal interface Measurement refresh speed Modbus RS-485 (SDI-12 optional) < 1 second max. Dimensions Weight Material in contact with the medium Maximum Pressure Cables/ Connection hardware and software Diameter: 25 mm; Length without cable: 146 mm 450g (with 3 meter cable) 316 L Stainless steel 5 bars 9-wire shielded cables, polyurethane jacketed, Fischer watertight metal shell connector Sensor identification Serial No. Screw-on strainer for capsule replacement ponsel@ponsel-web.com, wwww.ponsel-web.com 7

8 OPTOD sensor maintenance : -The OPTOD sensor must always be kept clean, particularly in the vicinity of the DO disk. Any trace of biofilm could lead to measurement errors. -After each use, rinse the sensor before storing. -If the membrane is dirty, clean the sensor head with warm water and soapy water. Use a sponge, but never use abrasive sponges with a scouring pad. Rinse the sensor before storing. Oxygen Calibration : The OPTOD sensor is an optical sensor which only requires an annual calibration. Using a clean sensor, periodically check the 0 % Sat value by immersing the sensor in a water/sulphite solution (sulphite concentration: < 2%). If the zero point is offset, perform a complete calibration of the sensor. Caution: do not leave the sensor in contact with the sulphite solution for more than one hour. The 2-point calibration is performed with a sulphite solution (offset). After rinsing and drying, the sensor s slope is calculated by exposing the sensor to humid oxygen saturated air. Temperature Calibration: Temperature sensor calibration is performed once a year in two stages: stage 1 (offset): the sensor is placed in a container filled with water and ice, stage 2 (slope): The sensor is placed in a medium (air or thermostat-controlled water) with a known temperature. This temperature will be measured using a certified thermometer. Changing the DOdisk : If you notice an offset in measurements during use, clean the sensor and calibrate it. If calibration cannot be performed, change the membrane support containing the sensitive material, proceed as follows : Unscrew the stainless steel strainer, Remove the DOdisk fitted onto an optical window. If this operation proves difficult (membrane stuck to the optical window), immerse the sensor in a little water to moisten the membrane and try removing the DOdisk using a small tip. Do not use a sharp object or screwdriver. This could scratch the optical window. Once the membrane is removed, be careful not to touch the optical window and reposition the DOdisk onto the optical window with the red side facing the window. The size of the disk is perfectly adjusted to fit the optical window. Refit the stainless steel strainer onto the sensor head and screw back on.

9 PNEPA : Turbidity/temperature sensor The measurement principle of the turbidity sensor is based on nephelometry: A LED emits an infrared light (880nm) and a receiver diode placed at an angle of 90 measures the light radiation emitted (standardized measurement). You can calibrate the sensor using a Formazine standard. This optical technology is a very cost-effective solution requiring little maintenance and no consumables (nonaggressive lens cleansing). Technical specifications: Measurement principle / Nephelometry 90 IR emission ISO 7027 compliance 0 to 4000 NTU in 4 ranges : NTU Measurement ranges NTU NTU NTU Resolution 0.01 to 1 according to NTU range Accuracy +/-1 % of the full scale per range Response time < 5 s Operating temperature 0 C to +50 C Temperature compensation Via CTN Temperature measurement range 0-60 C Temperature resolution 0.01 Temperature accuracy +/- 0.5 C Storage temperature -10 C to + 60 C Signal interface Measurement refresh speed Modbus RS-485 (SDI-12 optional) < 1 second max.

10 NTU sensor maintenance: Keep the NTU sensor clean, particularly the head containing the optical fibers. Any trace of biofilm or dirt could lead to measurement errors. After each use, rinse the sensor before storing. If the sensor head is dirty, clean it with a little warm water and soapy water. Use a sponge, but never use abrasive sponges with a scouring pad. Rinse the sensor before storing. Turbidity Calibration: The NTU sensor is an optical sensor requiring little calibration. Using a clean sensor, periodically check the NTU 0 value by immersing the sensor in still distilled water. If the 0 point is offset, perform a complete calibration of the sensor. To do this, you need a Formazine solution with a concentration equal to half the measurement range. Prepare the solution by using a stock solution at 4000 NTU. To prepare the solution, use a 200mL volumetric flask. Add the required volume of Formazine (see table below) and make up to 200 ml with distilled water. Formazine solution with concentrations below NTU degrade quite quickly. Do not keep the solution for several days. The 2000 NTU solution can be stored for 2 to 3 weeks in an opaque bottle in the refrigerator. Measurement range Formazine calibration solution concentration Volume of Formazine (ml) NTU 25 NTU 1.25 ml NTU 100 NTU 5 ml NTU 500 NTU 25 ml NTU 2000 NTU 100 ml Temperature Calibration: Temperature sensor calibration is performed once a year in two stages: stage 1 (offset): the sensor is placed in a container filled with water and ice, stage 2 (slope): The sensor is placed in a medium (air or thermostat heated bath water) with a known temperature. This temperature will be measured using a certified thermometer. ponsel@ponsel-web.com, wwww.ponsel-web.com 10

11 PC4EA conductivity/temperature sensor The electrode operates with 4 electrodes technology: a constant voltage alternating current is established between two graphite primary electrodes. The platinum secondary electrodes regulate the voltage on the primary electrodes according to the degree of fouling. The voltage measured between the primary electrodes is a function of the resistance of the medium and, therefore, of conductivity. Technical specifications: Measurement principle Conductivity sensor with 4 electrodes (2 graphite, 2 platinum).

13 PHRTA ph/redox/temperature sensor The dual stage PONSEL ph/redox/t C sensor consists of : - an electronic part - a consumable part The sensor is dual stage on delivery and only the consumable part requires replacement when the calibration gel is depleted. The measurement principle includes an Ag/AgCl reference electrode with PLASTOGEL KCI saturated plasticized electrolyte used for ph and Redox measurements The Plastogel electrolyte is in direct contact with the external environment without the use of capillary or porous material. There is therefore no danger of blockage or unpriming of the calibration material. The measurement electrodes come in the shape of special ph sensitive glass phials welded to the end of a crystal tube, for ph measurements, and platinum tips for Redox. Temperature measurement is performed via CTN inserted in a stainless steel houding. ph measurement Measurement principle ph/reference combined electrode: Special glass, Ag/AgCl Reference Gelled electrolyte (KCI) Measurement ranges 0 14 ph Resolution 0.01 ph Accuracy +/- 0.1 ph ORP measurement ORP measurement principle Redox/Reference combined electrode: Platinum tip, Ag/AgCl Reference Gelled electrolyte (KCI) Measurement range to mv Resolution 0.1 mv Accuracy ± 2 mv Temperature measurement Temperature measurement principle CTN Operating temperature 0.00 C to C Resolution 0.01 C Accuracy ±0.5 C GENERAL Storage temperature -10 C to + 60 C Signal interface Modbus RS-485 standard supply (SDI-12 optional) Measurement refresh speed < 1 second max.

15 CHAPTER 4 USING THE ODEON 4.1 Power supply Type of batteries authorized Users should never combine different types of batteries or connect a charger to an ODEON fitted with alkaline batteries. This could cause a fire hazard or explosions Changing the batteries Used AA alkaline batteries should always be replaced in a clean, dry place, to avoid any dirt entering the unit housing. The operator must first check that the batteries or rechargeable batteries are correctly positioned in the battery compartment (positive and negative polarity). When closing the unit housing, the operator should check: that the power cable between the battery unit and the electronic card is not caught, that the seal between the two halves of the housing is in place, that all 6 screws are tightened so that the seal is crushed between the two parts of the housing. Inadequate tightening will result in ODEON malfunction or leakage into the unit. The operator must also regularly check the batteries to avoid equipment damage due to old batteries Rechargeable batteries The 4 NiMH rechargeable batteries in the ODEON can be recharged without removing them from the unit. Use only the recharging cable supplied by the manufacturer. The unit housing may feel slightly warm during the recharging operation: this is normal. Users will note that the charger supplied with the ODEON is not watertight. Do not use in a damp environment (field work measurements) but only in laboratory conditions. The ODEON-PC USB connector is also designed for office use, not outdoor use. Users shall be entirely liable for any problems encountered while transferring data to a portable computer in the field (in damp environments) Prolonged storage or use NiMH accumulators will lose power when not in use. Before starting a measurement campaign, uses should check the charge level indicated by the icon displayed in the upper right-hand corner of the screen. If the output voltage of the batteries or accumulators is too low, the screen will start blinking, then the unit will cut out altogether. However, any data already saved will remain safe. When preparing for a long measurement campaign, users should fit new alkaline batteries or recharge the accumulators. Users may also connect the ODEON to an external 12V source via the optional connector cord. ponsel@ponsel-web.com, wwww.ponsel-web.com 15
