Based on the NDIR principle and adopts digital precession technology as zero point/range point calibration, linear processing, temperature compensation, switch output, flow/voltage output, parameters setting. Such as digital pulsed infrared source, high sensitive infrared sensor. It can be used for detection for different concentration and different gases as (SO2, NOX, CO2, CO, CH4 etc).
Features NDIR, sensor does not touch tested gas, sensor poisoning will not happen. Good intelligence, stability, high reliability and long calibration cycle.. Measuring cell with gilded mirror can be corrosive-resistance. Large LCD display. 4-20mA/0-20mA/0-10V output optional. Two-way single-pole single throw alarm function. Menu lock function. Latest touch key technology. Timing automatic storage function, which you can check store data at will;
