Product Description
Portable Multi gas detector
A Portable multi gas detector is a portable device designed to detect multiple gases simultaneously. A portable multi gas detector is usually the last line of defence to alerting operators out of dangerous gas leaks. The most common sensor configuration for a Portable multi gas detector is carbon monoxide,hydrogen sulfide,flammable (infrared or catalytic) and oxygen. We also can add CO2/H2/NO2/NH4 in this device to meet the clients requirements.This configuration is commonly used for confined space entry, the SA500 Portable multi gas detector is the perfect detector for this hazards application.
We offer a range of multi gas detectors for you to choose from, like Multi gas detecting alarm,Single gas detector,2 in 1 gas detector,3 in 1 gas detector,4 in 1 gas detector,4 gas detector,portable multi gas detector,Vehicle gas detector.View our gas detectors choices below. You can also get a reliable single gas H2S gas detector,O2 gas detector,CO gas detector, CH4 gas detector and more at SA Technology.

Working principle
In this Portable multi gas detector device,the methane/combustible gas sensor adopts hot catalytic working principle and it consists of black and white elements inside.The black element is the catalytic carrier of methane/combustible gas,and will occur thermal catalytic reaction with the methane/LEL gas to change its own resistance value;the white element is a pure carrier and its resistance value is stable.According to this sensor's characteristics the single is enlarged by the wheatstone bridge and displays the value,thus concentration detection methane/combustible gas is achieved.
The CO sensor,O2 sensor and H2S sensor all adopt electrochemical principle.The inside electrode will react with the being detected gas in the role of catalyst to achieve the directional movement of electron between electrodes,and make the electrical single amplified and displayed by amplifying circuit technology and other existing technologies so that to achieve the detection of concentration
