7 Page 7 of 8 Steps to Selecting a Specific Ion Electrode Mounting In addition to ph there are a number of other ions that can be measured by electrodes that are manufactured with membranes that are specific to that particular ion concentration. Honeywell offers three electrodes for specific ion measurements - sodium, fluoride, and chloride. These electrodes can be mounted in the 7773 ph assembly for either immersion or in-line mounting. This assembly provides a housing for mounting a measuring electrode, reference electrode, and temperature sensor. In addition, the preamplifier is also mounted in the assembly. A 7082 or 9782 Specific Ion Analyzer is used to display the measurement, provide output and relay capability, and perform calibration. Other specific ion measurements can be made using other suppliers electrodes. Among these are ammonia, bromide, cadmium, cyanide, iodide, lead, potassium, silver, and water hardness, to name a few. The ability to make these other ion measurements must be pre-qualified based on electrode documentation from the supplier. A complete specific ion-measuring loop consists of a measuring electrode, reference electrode, temperature sensor, preamplifier in a mounting assembly, and an analyzer. Below is the procedure to catalog a complete loop: Electrode Mounting Assembly, Preamplifier, and Temperature Sensor _ (Tag Option) 1 In-line, polypropylene 2 Immersion, polypropylene 3 In-line, stainless steel 4 Immersion, stainless steel 5 In-line, stainless steel flow chamber, polypropylene cover Refer to MSG for complete pricing and explanation of table selections and tagging options. Electrodes Honeywell can supply the following measuring electrodes: P/N Type Sodium Fluoride Chloride

8 Page 8 of 8 Honeywell recommends the following reference electrodes: P/N Type Service Single Junction, KCl filled Fluoride Double Junction Chloride Single Junction, calomel filled Sodium Refer to Replacement Electrodes, Section 2, Page RE-1, for electrode pricing. For other ion measurements omit the P/Ns for the measuring electrodes and order from outside supplier. The reference electrode selection for another suppliers measuring electrode should be based on the suppliers recommendations. Order the appropriate reference electrodes, based on this recommendation, from Honeywell. Cable Cable connections from the electrode to the preamplifier are done in the 7773 housing using cables supplied with the electrodes. An additional cable needs to be ordered to make the connections between the preamplifier and the analyzer. This cable is ordered by the foot and is P/N If using another supplier s measuring electrode it may be necessary to modify the connections within the 7773 mounting. For these modifications it is recommended that the customer purchase two additional items. The first is a shorting cable, P/N and the second is an extra terminal, P/N Current prices for the cables and terminal are available on the OMS or COPS order entry systems. Analyzer Model XX Standard unit 75 CE Compliant unit Refer to MSG for Table II options for the X s and pricing. OR Model 9782S - 0M - XX - EXXX0-00 Refer to MSG , when available, for Table II and III options for the X s and pricing.
