Control unit RD-3000А
The RD-3000A control box is an intelligent interactive monitor control box designed to meet the environmental monitoring needs of industrial production. It can detect the content of the measured gas in the environment by connecting to the sensor unit. When the content of the measured gas in the environment exceeds the norm, a real-time alarm should be triggered. It has the functions of temperature and humidity detection, working status voice query, remote alarm and history query, etc. This system can be widely applied in petroleum, metallurgy and petrochemical industries, etc.

Key Features
- Displaying a list of logs by history reports for staff requested
- Extra wide design of 185 ~ 265V AC working power supply, preventing surges.
- Sturdy mounting structure, low maintenance
