Description
Overview
GAOTek explosion proof gas detector is the company’s latest introduction of a multi-line combustible gas alarm controller, with a continuous monitoring and display environment of combustible toxic gas concentration value, and in the control room or duty rooms real-time display and sound and light alarm, when needed can be linked control. The alarm also adopts the domestic advanced PWM power supply control technology, which makes the alarm stable and reliable. The advantages of fast response speed and strong anti-jamming force, at the same time, the alarm can be customized according to the requirements of the field environment explosion proof shell, suitable for all kinds of complex monitoring environments. More than 8 hours of continuous operation when an optional high-performance backup power supply is available.
Features
- High brightness display, long distance Linhuan to see the value of clear
- There is a power outage memory function that maintains the working state
- Advanced fuzzy control judgment to reduce the occurrence of false alarms
- With a one click Reset function, easy to operate
- High decibel alarm sound to the alarm information to prompt (alarm sound > 85 dB)
- The number of channels can be set arbitrarily by one to eight channels
