Overview
These series are single-gas detectors. When the concentration of the gases in the operating site reaches or exceeds the preset value, it will send a sound and light alarm. International standard 4-20mA signal output, can be directly connected to the factory DCS system(optional); RS485 digital signal can be connected with the factory’s principal computer(optional).
Features
- Adopts advanced embedded micro controller(16 digit ultra-low power consumption )
- 128*64 dot matrix ultra-large LCD
- The user can set the alarm level
- Displaying the time of the first alarm
- Real-time clock
- Replaceable modularized sensor
- Automatic calibration function reduces the measuring error.
- Automatically save alarm data for 1000 articles
- standby battery can work more than 100 hours under the condition that there is no alarm (optional)
- standard signal(4-20mA) can be directly connected to the factory’s DCS system (optional)
- digital signal is connected to the factory’s principal computer (optional)
