Features
1) Wall mounting, real time detect CO with measuring range of 0~500ppm.
2) With Japanese semiconductor CO gas sensor inside. More than 5 years lifetime.
3) Full time indicate CO level, even the slightest leak can be detected
4) Specially design with six indicator lights indicate six different CO level ranges.
5) One on/off output optional for control a fan or another device such as an alarm.
6) Different CO level corresponds with different light indicating. Four setting CO value ranges can be selected to control the relay output via a set of jumpers.
7) RS-485 communication interface optional with 15KV antistatic protection, independent address setting.
