VTSYIQI PH3 Gas Detector PH3 Gas Tester Phosphine Detector with  Measuring Range 0-20ppm Resolution 0.01ppm Sound & Light Alarm Wall Mounted Installation Standard 4-20mA and RS485 

Feature：

Detection gas: PH3 Phosphine Gas; Range: 0-20ppm; Resolution: 0.01ppm

Adopt the original Swiss imported sensors

Three-wire 4-20mA analogue and RS485 signal outputs as standard

Infrared remote control can be remote non-open cover to achieve the alarm point setting, zero calibration, modify the address and other functions.

Monitoring the gas concentration in the environment or pipeline, full software auto-calibration function, zero calibration function, make gas monitoring more accurate and reliable.

Product overview:

Adopt the original Swiss imported sensors

Three-wire 4-20mA analogue and RS485 signal outputs as standard

Compatible with a variety of control alarms, PLC, DCS and other control systems, remote monitoring can be realised.

Explosion-proof design, fast, reliable and stable; explosion-proof grade Ex d II CT6

Full software auto-calibration function, the machine is equipped with standard three keys to achieve single person single point on-site maintenance.

Monitoring the gas concentration in the environment or pipeline, full software auto-calibration function, zero calibration function, make gas monitoring more accurate and reliable.

With temperature compensation, it can perfectly realise the compensation of gas concentration under different ambient temperatures.

Infrared remote control can be remote non-open cover to achieve the alarm point setting, zero calibration, modify the address and other functions.

One or two switching signals can be output to drive external devices such as exhaust fans or solenoid valves.
