CO concentration and temperature detection and control applied to the environment, monitoring ventilation systems, effectively reducing energy consumption (note: Building ventilation, energy conservation, and related standards stipulate that in buildings such as garages or motor vehicle maintenance and operation workshops, ventilation systems should be started and stopped according to usage, or automatically operated based on CO concentration).
The service life is up to 3-5 years.
Digital technology application, multiple output options, overvoltage and reverse connection protection measures, high reliability and anti-interference ability.
Lightweight shell, beautiful and elegant, easy to install.
Multiple output modes are available, and relay output can be selected to achieve alarm or control functions.
It has multiple parameter setting, modification, and calibration functions, and can achieve independent control functions.
