The portable hydrogen detector is used for portable and rapid detection of hydrogen gas concentration and alarm when exceeding the standard. The hydrogen detection alarm uses a high-definition color screen to display the concentration in real time, and uses a well-known brand of gas sensor. The main detection principles are: electrochemistry, infrared, catalytic combustion, PID photoion, semiconductor/thermal conductivity.
Electrochemical NO2 sensor can be used for gas concentration detection and concentration exceeding alarm.

The smoke sensor is a common fire warning device. It has the function of early detection of fire signals. It can accurately sense the smoke produced by the fire in the early stage of the fire. Its working principle is that when the substance burns, it will often produce smoke first. , And then produce visible and invisible light, and there is always a process from the beginning of the burning of the material to the time when the fire gradually increases. The smoke detector will “capture” the “signal” when the material is burning, and “capture” the The “signal” is converted into an electrical signal, which is transmitted to the controller of the automatic fire alarm system, which promptly warns people and informs relevant personnel to put out the fire.
The oxygen detection sensor can detect the oxygen gas concentration in the pipeline or in the confined space and the atmospheric environment. It can also detect gas leaks. It can detect more than 1,000 types of gases. It can also detect the purity of a single gas with a high concentration of nitrogen or oxygen as a variety of background gases. .
Generally speaking, the portable methane gas detector adopts tunable laser diode absorption spectroscopy technology, which has high sensitivity, fast response speed, and good selectivity. It only reacts to methane and will not produce false alarms to other hydrocarbon gases. So what are the main functions and technical characteristics of the portable methane detector?
The combustible gas alarm is an intelligent combustible gas detector. The combustible gas alarm uses a stable and reliable semiconductor sensor. It protects the monitoring scene from the threat of combustible gases (such as liquefied petroleum gas, natural gas, methane, etc.).
