    High performance handheld gas detector is a suction and diffusion dual-purpose device. When the air pump fails or in special emergency situation, it can automatically switch to the diffusion sampling method, thereby improving the protection to a new level.


    • The portable gas detector can effectively resist a three-meter drop, has passed the EMC anti-static interference test and can work normally in the walkie-talkie environment.
    • It has got IECEX, ATEX, explosion-proof certificates and the explosion-proof level reaches Exia IICT4 Ga. The man down alarm function has upgraded the safety of underground operators.
    • Password protection function prevents non-operators from modifying menu parameters. With safety reminder function, sound and light vibration alarm function, let operators work without worries. The high and low alarm latched function allows the operator to better capture the sudden change of the gas concentration value.
    • Real-time value, TWA, STEL, MAX, MIN multiple numerical display, and the screen can be automatically turned 180 degrees, which is convenient for viewing in special operating environments.
    • Built-in powerful sampling pump, fast detection speed. It can be connected 20m sampling tube externally, which is convenient for long-distance or confined space detection.
    • Pump suction and diffusion dual use, to provide operators with more reliable protection. With a water trap filter, it can effectively filter water, oil, dust and other impurities. It can also be used in harsh industrial environments such as coal mines and petroleum fields.
    • Beautiful and friendly user interface, reasonable and easy-to-use interactive mode. Standard storage function, one-click data export, convenient for users to analyze.
    • Unique modifiable ID identification function, convenient for users to allocate and manage the instrument. A full range of automatic detection functions, automatic prompts for voltage, pump failure alarms, etc., more comfortable to use.
    • One-key open storage, automatic image flip. It supports each channel sensor to restore the factory setting separately and multi-language including English, Chinese and etc.

    Applications of Portable Multi Gas Detector

    Tips: How to maintain portable gas detector?

    • Check the gas flow rate, usually 30/h. Excessive or too small flow will have a greater impact on the analyzer results.
    • Replace the filter paper: stop the air pump and drain the filter tank.
    • Check whether there is any air leakage in the gas system. Whether the diaphragm of the sobbing pump is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and condensate are damaged, etc.
    • Cleaning the sampling probe and dredging the sampling hole pipeline
    • Check whether the condenser is working normally, usually the temperature is adjusted within 3℃.
    • Check the measuring device room to see if it is dirty, and clean it in time.
