Jinan Jincheng Security Equipment Co., Ltd. is a professional manufacturer specializing in the research and development, production, and sales of gas detectors. The portable single gas detector produced is an instrument that can continuously detect the concentration of toxic, harmful, flammable, and explosive gases in the working environment. The detector detects gas concentration through natural diffusion, using imported sensors with good sensitivity and excellent repeatability; Automatic startup detection, with advanced self diagnosis and self repair functions; The instrument adopts embedded microcontroller technology, with simple menu operation, complete functions, high reliability, and multiple adaptive capabilities; Using LCD Chinese character display screen, intuitive and clear; Fault and undervoltage indication, the screen display can rotate 180 degrees, making it convenient for people with different habits to use. The ergonomic design provides a comfortable grip and simple operation.

This instrument can save 3000 alarm records, which can be viewed by pressing a button or transmitted to a computer through a USB interface. After being equipped with upper computer software, it can be further analyzed; Can set alarm points, calibrate, and read, print, and save alarm records, etc; 1500mAh large capacity lithium battery greatly improves device battery life; Using USB interface for charging, the universal charger is convenient for charging.
The shell of this detector is made of refined polycarbonate material and composite elastic rubber material, with high strength, temperature resistance, corrosion resistance, and good hand feel. This product is suitable for detecting the concentration of toxic and harmful gases in the ambient air, and is widely used in metallurgy, power plants, chemical industry, mines, tunnels, underground pipelines and other places, effectively preventing accidents from occurring.
