Toxic and harmful gas detectors are gas detectors specifically designed for the petrochemical industry, with exquisite appearance, complete functions, and suitable for various occasions;Simultaneously supporting HBUS and 4-20mA (HART) communication methods,Equipped with a built-in LCD display, the on-site gas concentration can be directly viewed through the screen, and alarm point settings, coefficient modifications, and other operations can be performed through the remote control,Built in OC leakage output, can be connected to an external sound and light alarm to expand the sound and light alarm function; It can also be networked with a combustible gas alarm control host, and both the power and signal ends are designed with no polarity.
Characteristics of toxic and harmful gas detectors:
Simultaneously supporting HBUS and 4-20mA (HART) communication methods, it has stronger compatibility;
*The detachable dust cover design, with a built-in cleaning dust net, can cope with various harsh environments;
Can be equipped with a specially designed rain cover for rain, drip, dust, etc
The detector adopts a backless design to prevent water ingress issues;
The detector has automatic identification and protection functions for over concentration, sensor short circuit, and open circuit faults;
Plug in sensor design, by connecting different sensor components, can achieve detection of different gas objects;
Replacing the sensor does not require calibration. The intelligent digital sensor component technology has good stability and strong anti-interference ability;
Adopting a wide temperature LCD display screen, it can achieve dual real-time display of digital and analog gas concentration;
Infrared remote control design allows for on-site calibration of the detector without the need to open the cover;
Built in OC leakage output, can be connected to an external sound and light alarm to expand the sound and light alarm function.
