Product Description
introduceThe YF-8400 series handheld diffusion monitoring device is capable of detecting combustible, hydrogen sulfide, oxygen, carbon monoxide, and four other gases. The detection principle is that when the target gas diffuses into the gas probe section, the internal sensor will immediately emit an induction. Sensors generate certain electrical signals based on the concentration of gas. After the signal is amplified and processed by the circuit, the CPU outputs accurate gas concentration data through AD sampling, temperature compensation, and intelligent calculation. Sound and light alarm, vibration alarm, data storage.
The waterproof design of the instrument is combined with a plastic casing, meeting the requirements for use in harsh environments. The product adopts diffusion sampling to measure gases, equipped with high-quality gas sensors, with high sensitivity and excellent repeatability. The instrument is controlled by an embedded microcomputer, with simple operation, complete functions, high reliability, and multiple adaptive capabilities. It uses a graphic and textual LCD display, which is intuitive and clear.
