Principle of GAS measurement

         Principle of GAS measurement


Generally, molecules absorb their own vibration and rotation spectrum when being radiated of infrared rays. Gas concentration in the sample is measured by using non-dispersive infrared ray analyzer by applying optical absorption at 7.3m(7,300nm) and 5.3m of infrared ray field.

Features of Gas Analyzer :


► Stable measuring can be made due to long life of infrared ray source.
► It has high response speed
► High-speed measuring can be made.
► It has less interference due to interruption ingredients.
► Easy maintenance can be made.
► It has good operation with high precision and multi-functions with microprocessor.
► It has built-in alarm function to output max/min contact output.
► Improvement of precision of Zero/Span calibration can be made easily by pressing each control key.
► Max. 1:20 range ratio is possible at standard two-range, by applying mass flow type detector with high speed and high reliability.
► Sample switching system and planetary differential system are also used for measuring besides standard system. Infrared ray source of light, rotation sector, sync signal, contact output, range identification signal, solenoid valve drive signal, output in the middle of calibration, transfer value, indirect compensation detector, detector AC voltage amplifier, gauge change, etc.
