1 Product Overview
This product is an intrinsically safe device that continuously detects gas concentrations. It is suitable for gas leakage and rescue in explosion-proof places, underground pipelines or mines, etc., which can effectively ensure the safety of workers and the production equipment is not damaged.
Portable gas detector uses natural diffusion method to detect gas. Sensitive components use high-quality gas sensor, which has excellent sensitivity and excellent repeatability. The instrument adopts embedded microcomputer control, simple operation, complete functions, high reliability, and various self-control. Adaptability; use dot matrix LCD display, intuitive and clear; small and beautiful portable design not only makes you love it, it is more convenient for you to use.
The portable gas detector shell is made of high-strength engineering plastic and compound non-slip rubber. It has high strength, good hand feeling, and is waterproof, dustproof and explosion-proof.
One button sets the full Chinese menu, “fool-like” operation, you can use it with your hands. The full range of the tested gas can set the alarm point and the battery voltage is displayed in real time.
