Complete factory calibration
Excellent long-term stability
Digital output
Linear voltage output
Excellent temperature performance
Dual-channel design
Robust metal structure Overview
IR-S is a gas sensor based on the principle of infrared absorption. Compared with traditional gas sensors, it has the advantages of good stability, strong selectivity, no oxygen dependence, wide detection range, long lifespan, long maintenance period, and strong anti-interference ability.
IR-S adopts a low-power processor, imported light source and dual-channel detector. It controls the overall power consumption while maintaining a constant sensor working current to ensure that the power supply circuit is not affected by current shock, ensuring the high efficiency, high accuracy and stable and reliable operation of the sensor data processing.
IR-S has digital signal output and analog voltage output, which is convenient for customers to choose applications. In addition, IR-S/CO2 provides customers with zero-point calibration and sensitivity calibration commands. At the same time, there are multiple baud rates and voltage ranges available for customers to choose.
Application
Industrial or mining gas concentration transmitters
Industrial or mining portable gas analyzers
Meteorology, agriculture, environmental air quality monitoring
Air quality monitoring in public places
Customizable measurement for other gases such as CO, SF6, etc.
