NDIR TYPE INFRARED GAS ANALYZER DATA SHEET ZRC6 This infrared gas analyzer measures the concentration of gas by utilizing the characteristic of gas (molecule consisting of different-kind atoms) that it absorbs the infrared ray of a specific wavelength. Stable and accurate measurement is ensured due to use of a mass flow sensor with a high sensitivity, interferencecompensating detector, etc. This analyzer is to be built in sampling equipment and optimally usable for measuring the concentrations of various gases. FEATURES 1. Most suited for incorporation in equipment This analyzer can be readily built in customer’s sampling equipment, because its analyzing block, signal processing circuit and power unit are all accommodated in a compact case. 2. High measurement accuracy and stability A single light source/double beam system, and a highsensitivity mass flow sensor ensure accurate and stable measurement. 3. Minimum influence by other gases An interference-compensating detector substantially suppresses interference by the disturbing gases coexisting in sample gas. 4. Wide dynamic range A range ratio of max. 1:20 can be secured in standard 2 ranges. Range selection follows the external selection input signal.
