Portable voice type multi gas detector is a safety device that can continuously detect the concentration of leaking gas. It adopts advanced integrated circuit technology, embedded
computer control, high-quality imported gas sensors, with excellent sensitivity and repeatability. It uses dot matrix LCD display to support Chinese-English interface and Chinese-English voice prompt, so that users can quickly understand the product and use and maintain it simply. High-strength engineering plastics, good seismic resistance, high strength, high-grade atmospheric appearance and dust-proof, waterproof and explosion-proof function, etc.

* When the detector is turned on, the LCD screen is in the standby state of displaying four concentrations of EX gas, O2, H2S and CO in real time.
* Light on the detector will voice the alarm signal. When the concentration of O2 gas is monitored by the detector and restored to the normal value, the alarm state of voice, light and vibration disappears.
* O2 concentration in normal air is 20.9%. Users can adjust the value of low and high alarm according to actual needs.
* When the concentration of H2S gas or CO gas is detected to be higher than the low alarm value set by the system, the detector will broadcast the voice "Please note that the concentration of H2S gas or CO gas exceeds the standard" and continue to simulate the alarm sound; the alarm lamp above the detector and the internal vibration motor will be turned on simultaneously; When the alarm value is low, the voice, light and vibration alarm states disappear.
