The HNB-H2-2 hydrogen concentration sensor adopts the principle of thermal conductivity and signal amplification treatment, and will output the corresponding hydrogen concentration in the way of analog signal. Can be used in the energy storage field and lithium battery electric vehicles of lithium battery thermal failure warning and detection, industrial and chemical field of hydrogen leakage detection, etc.The sensor can meet the detection of 0-20% hydrogen concentration, sensor signal and hydrogen concentration are linear output, and can be set at the free point.
