Hydrogen gas detector reacts quickly and accurately to hydrogen gas leakage. When hydrogen gas leakage occurs, it can alarm in time. It is the most commonly used instrument to detect gas in today's industrial field. It is mainly divided into the following three commonly used hydrogen gas detectors:

Portable hydrogen detector. The portable hydrogen leak detector can be carried around and can continuously detect the hydrogen concentration in the carrier's working environment. The hydrogen leakage detector adopts the natural diffusion method to detect the gas concentration, adopts the imported electrochemical sensor, and has excellent sensitivity and repeatability; the hydrogen detector adopts the embedded micro control technology, with simple menu operation, complete functions and high reliability.
2. Pump type hydrogen detector. The pump suction hydrogen detector adopts a built-in suction pump, which can quickly detect the hydrogen concentration in the working environment. The pump type hydrogen detector adopts imported electrochemical sensor, with very clear large LCD screen and sound light alarm prompt, which ensures that dangerous gas can be detected in dark light working environment and prompt to the operator in time to prevent danger
3. Online hydrogen detection alarm. The online hydrogen detection alarm consists of a gas detection alarm controller and a fixed hydrogen detector. The gas detection alarm controller can be placed in the duty room to monitor and control each monitoring point. The hydrogen detector is installed in the place where the gas is most likely to leak, and its core component is the gas sensor.
The hydrogen detector converts the hydrogen concentration detected by the sensor into electrical signal, which is transmitted to the gas detection alarm controller through the cable. The higher the gas concentration is, the stronger the electrical signal is. When the gas concentration reaches or exceeds the alarm point set by the alarm controller, the gas detection alarm controller will send an alarm signal and start the external equipment such as solenoid valve and exhaust fan to automatically eliminate the hidden danger. Online hydrogen detection alarm is widely used in petroleum, chemical industry, metallurgy, electric power, coal mine, water plant and other environments to effectively prevent the occurrence of explosion accidents.
