Features of carbon monoxide detector
1. The wall-mounted waterproof shell is adopted, which is convenient to install and has high protection level.
2. Optional high-quality OLED display, the value can be viewed directly on site, and can be displayed clearly at night.
3. Imported first-line brand electrochemical sensors are used, which is stable and durable.
4. The on-site power supply adopts 10~30V DC wide-voltage power supply, which can adapt to a variety of on-site DC power supplies.
5. The output modes are: rs485/4-20mA/0-10V/0-5V.
