HNB-H2-2 Hydrogen Concentration Sensor Thermal Conductivity Principle

HNF-H2 is a hydrogen concentration sensor based on the thermal conductivity principle, 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 has the characteristics of fast response time (<1 second), low power consumption, long life, large 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 in the thermal conductivity of the hydrogen mixture. This sensor chip is suitable for hydrogen concentration detection and real-time leakage monitoring in places such as hydrogen production, hydrogen storage, hydrogen supply, hydrogen fuel cells, and lithium battery thermal failure. The detection range of hydrogen concentration is 0-100000ppm.
