4 in 1 Gas Detector ABH-840 Introduction

The voice-type four-in-one gas detector (hereinafter referred to as the detector) is a safe device that can continuously detect the concentration of leaked gas. it adopts advanced integrated circuit technology, embedded microcomputer control, high-quality imported gas sensor, with excellent sensitivity and excellent repeatability;

Using a dot-matrix LCD display, supports Chinese and English interfaces and Chinese and English voice prompts, users can quickly understand this product, it is easy to use and maintain; the shell is made of high-strength engineering plastics, with good shock resistance, high strength, high-grade appearance and dust-proof, waterproof and explosion-proof functions.

This detector is widely used in petroleum, chemical, environmental protection, metallurgy, refining, gas, biochemical medicine, agriculture, fire protection, archaeology and other industries and places that need to safely monitor toxic and harmful gases and prevent explosions.

The detector can effectively predict the dangerous gas concentration and alarm to ensure that the life safety of the staff is not threatened and the production equipment is not damaged.
