Description
Overview
GAOTek ammonia gas detector is a fixed gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. It shows no: only the concentration of gas but also diagnostic result of the unit itself through the LCD screen and can be connected to the control panel with a standard 4 mA to 20 mA analog output or RS435 digital! communication.
Features
- Smart sensor module design, easy for replacement
- Built-in buzzer and flasher
- Measures the concentration of the flammable gas, toxic gas,
- Oxygen and VOCs
- Explosion proof structure.
- Water and dustproof design
- LCD screen display
- IR remote control for setting and calibration.
