The fixed hydrogen gas detector is applicable to hydrogen concentration detection and leakage real-time monitoring in fixed places such as hydrogen production, hydrogen storage, hydrogen supply, and ships. The hydrogen concentration range is 0-40000 ppm. It adopts the principle of aerobic catalysis and signal power amplifier, which has the advantages of fast response, high measurement accuracy, good stability and repeatability. The explosion-proof armor and wiring mode are applicable to various dangerous places. The analog signal output is adopted for the corresponding hydrogen concentration, and the signal is linear output. The warning point can be set at the free point. At present, there are three signal modes: analog signal, PWM signal and CAN signal. The corresponding models are HNE-H2-2 (analog output signal), HNE-H2-2C (CAN output signal) and HNE-H2-2P (PWM output signal)

HNF-H2 is a hydrogen concentration sensor based on the thermal conductivity principle, which is suitable for detecting hydrogen concentration. The sensor consists of a detection element chip (HNF-H2-CS) and a compensation element chip (HNF-H2-CR). It is characterized by fast response time (< 1s), low power consumption, long life, large measuring range, high measurement accuracy, high stability and reliability, and low cost. Since hydrogen has the highest thermal conductivity among all known gases, it is possible to detect the hydrogen concentration by detecting the change of thermal conductivity of hydrogen mixture. This sensor chip is applicable to hydrogen concentration detection and leakage real-time monitoring in places such as hydrogen production, hydrogen storage, hydrogen supply, hydrogen fuel cell, lithium battery thermal failure, etc. The detection range of hydrogen concentration is 0-100000ppm.
