This new arrived fixed single gas transmitter is an intelligent control product developed by Huafan company,can detect gas concentration by natural diffusion with remote control key,LCD large screen display in real time, time and calendar display,DC24V working voltage, can store 3000 + data records,can output 4-20 mA current signal and RS485 digital signal.
This product has high stability, high accuracy and high intelligent characteristics, and through simple operation you can realize control and alarm to test area. It’s mainly used in the area need to detect combustible gas, oxygen, and other poisonous gas, can display the real time concentration value of detected gas, when detected gas index beyond or below pre-set standard, the system automatically do a series of alarm action, such as alarm, exhaust, tripping, etc.
