Depending on the concentration range for hydrogen detection, there are two types of sensors to choose from:
1. If you need to detect very small amounts of hydrogen (10-6, i.e. 1ppm, parts per million volume ratio), you need to use itelectrochemicalhydrogen sensor, the detection range is 0-1000/2000ppm.
2. If the purpose of the detection is to prevent hydrogen leakage and combustion explosion, the LEL probe can also be used for this property, that is, the catalytic combustion sensor can be usedFlammable gas detection head。
Compared with the two detection solutions, the former has high price and high accuracy; The latter is inexpensive but insensitive to very small amounts of hydrogen. The above values are for reference only and are not used as a basis for selection. Please choose the type according to the specific situation of the site and the suggestions of experts or design institutes. For details, please consult: 010-87008500 010-51292816
The hydrogen detection alarm used in industrial sites can be divided into fixed online hydrogen detection alarm and handheld portable hydrogen detection alarm.
The fixed online hydrogen detection alarm system is divided into two types: multi-wire system and bus system.
It is composed of two parts: hydrogentransmitter/probe and gas alarm control host, and the multi-wire host can be divided into single-channel, dual-channel, four-channel and eight-channel. (Each channel means one hydrogen probe can be attached)
Hydrogen detection probes with digital display can be equipped on site or imported hydrogen detection probes.
If you only want to detect the explosiveness of hydrogen and use it for safety alarms, instead of measuring the concentration display of hydrogen ppm level, you can choose a flammable gas detection alarm, which will be more cost-effective.
