Description
Overview
GAOTek portable 4 in 1 multi gas detector monitor- automatic shutdown is an instrument that can use continuous monitoring four different gas: Ku, H₂S, Oneon , Li, when these gases are detected, all focus will display on the LCD. The module also provided the user to configure high and low alarms, it also has STEL or TWA alarm function. The unit has an acoustic visual alarm and vibration as soon as the ARN state is exceeded.
Features
- Detection of 4 types of gas: carbon monoxide (CO), hydrogen sulfide (H₂S), oxygen (O₂) and combustible gas (LEL).
- Continuously monitor CO, H₂S, O₂ and LEL gas concentration in the surrounding environment with professional and accurate measurement
- Sound and light tracking bracelets with vibrating alert works when one of CO, H₂S, O₂ & LEL gas concentration reaches the alarm level.
- Can set automatic shutdown time and focus alarm value.
- Large color LCD display with backlight for easy reading.
- Can connect to the sampling pump to work in an enclosed space.
