NDIR TYPE INFRARED GAS ANALYZER

Transcription

1 DI T ID S DT ST This DI gas analyzer is used for measuring CO, CO, SO and C 4 and features a high accuracy, multiple functions and easy operation through use of a microprocessor. It is housed in a 19 inch rack case suitable for mounting on a panel or a table-top. The analyzer provides a performance superior to the conventional double-beam system, is easy to maintain, and offers an excellent long-term stability. It is thus optimum for continuous measurement in the combustion control of various industrial furnaces, in research on garden-plants, and so on. TS 1. The use of a microprocessor provides high accuracy, multiple functions and easy operation. ero and span calibration is accurate and easy just by pressing the calibrating keys. self-diagnosis function is included. n automatic calibrating function can be provided as an option. ange can be changed over by a external signal as an option.. n improved optical system provides long term stability, and there is a minimum of drift caused by contamination of the measuring cell, so the long-term stability is excellent. 3. dopting a serial dual-layer type of transmission detector minimizes remarkable the interface from other gas components. 4. asy maintenance. The single-beam photometric system uses a sample cell only and eliminates the necessity of delicate adjustment for optical balance. The instrument is designed as a unit of simple construction featuring easy maintenance and checks.
