product overview:

portable gas detector (hereinafter referred to as the detector) is a safe device that can be used continuously to detect the concentration of leaked gas. It adopts advanced integrated circuit technology, embedded microcomputer control and high-quality gas sensor, with excellent sensitivity and excellent repeatability. Using high-resolution TFT display screen and supporting text interface, users can quickly understand this product and operate and maintain it simply. The shell is made of high-strength engineering plastics with high strength, good seismic performance, high-grade atmosphere and dust-proof, waterproof, explosion-proof, easy to carry and other functions.

Industry Applications:
This detector is widely used in petroleum, chemical, gas, environmental protection, metallurgy, refining, biochemical medicine, fire protection, agriculture and other industries and places that require safe monitoring of combustible gas, toxic and harmful. The detector can effectively predict the dangerous gas concentration alarm, to ensure that the life safety of the staff is not threatened, the production equipment is not lost.
