Brief Introduction

PGas**1 Series Single Gas Detector has high sensitivity and high accrancy, it is suitable for the detection of many kinds of toxic and harmful gases.It is used to detct the concentration of many kinds of gases such as flammable gaes(H2, CH4,C2H6,fuel gas,lpg gas,natural gas),O2,H2,CO,CO2,H2S,NH3,Cl2,SO2,NO,NO.It will alarm( sound/light/vibration ) once the content of target gas reaches or exceeds the preset alarm point to guarantee the safety.Users can set the upper/lower alarm points according to practical need.

 

The instrument adopts advanced **-bit microcontroller with extra low power consumption and quick processing speed. It is firm and durable with the anti-skid design of shell. It is widely used in petroleum, petrochemistry, chemical industry, gas, coal, metallurgy and power system; safety detection in municipal administration, communication and traffic tunnel construction; electronics and semiconductor industry and other places where toxic and harmful gases exist.
