Overview
Hospitality Enviro Tech Carbon Dioxide Detector The portable multi-parameter gas detector is designed to meet the needs of coal mining industry. It can be used to detect the concentrations of methane (CH4), carbon monoxide (CO), and oxygen (O2) in the working environment underground in coal mines.
Features
- High explosion protection level
- Smart and easy to operate and maintain
- Display mode can be switched
- Real-time or timed detection supported
- Multiple alarm modes and alarm mode settings
- Not affected by zero drift during long-term use
- OEM or ODM supported
