Product Description:
The DN1000 series gas alarm controller can be applied to the measurement and control of various signals, such as 4-20mA signals, RS-485 signals, and TCP/IP network interface devices.
The electronic circuit adopts advanced high precision micro-controller processing technology, which makes the controller work stably with high measuring precision and strong generality.
The system adopts Andriod operating system. Therefore, it has user-friendly operation interface, powerful system function. Operating the system menu through buttons, the main display screen displays gas detector concentration value, alarm information, fault information and other information.
