Detail Information

Product Introduction

 

The SRE1012 hydrogen sensor is a catalytic combustion gas sensor developed based on nanotechnology. The sensor has good stability, reliability and test accuracy, and can be used to detect hydrogen gas concentration in different scenarios.

 

In addition to sensors, our company also provides complete detection modules which include test circuits and algorithms for direct use.

 

Main Applications

 

● Hydrogen alarm instrument

● Hydrogen concentration test analysis

● Hydrogen leak detection for hydrogen powered vehicles

● Hydrogen leak detection at hydrogen fueling station

 

Sensor Characteristics

 

● Low temperature drift ( <1.5mV )

● Wide measuring range

● Fast response and recovery

● High precision

● Strong anti-interference ability

● Anti -poisoning by HMDS, H2S , SO2 , etc.

● High stability and reliability
