Split gas detection module
SKA/NE-101 type split gas detection module is a standardized and modular product for 24-hour online monitoring of specific concentrations of toxic and harmful gases in the air. Use advanced foreign original imported sensors, long service life; Select high-precision operation amplifier and power IC, through the 32-bit microprocessor and 24 data collector, and then carry out the full range of temperature and humidity compensation, and then use standard gas calibration, calibration; Stable performance, sensitive and reliable; Can accurately detect low or high concentrations of toxic gases; Product safety circuit design, strong anti-interference ability, over range protection, reverse polarity protection and lightning protection; Product design low power consumption, direct output 4~20mA, RS485, TTL and 0~5V optional; Module installation mode: pump type, diffusion type, flange type, flange thread type is optional. Can detect CO, H2S, NH3, HCN, PH3 and other toxic and harmful gases.
Foreign original imported sensors, using intrinsic safety technology, can support multi-gas, multi-range detection, and can provide customized products according to user needs.
Optional 1~2 groups of relay (switching signal) signal output, easy to use with the fan or solenoid valve control equipment.
Intelligent temperature and zero compensation algorithm, so that the instrument has better performance and excellent selectivity, to avoid the interference of other gases to the detected gas.
32-bit microprocessor + 24-bit acquisition chip, can detect at any point in the value of 00.000~99999.
Various range units are available: %LEL, %VOL, PPM, PPB, μg/m3.
A variety of signal output options: 4~20mA, RS485, RS232, 0.4~2V, 0~5V, etc.
