Gas Alarm Systems supply self-calibrating, maintenance free, dual beam, gold plated infra-red detector. The self-calibrating CO2 detector/monitor ranges from 0 to 5% Vol CO2. Here the micro-computer self calibrates based on background CO2 levels.
Self-calibrating CO2 detector/monitor from Gas Alarm Systems works on infra-red sensing technology. Due to its ABC feature (Automatic Background Calibration), it self-calibrates itself based on background CO2 levels. The sensing technology is based on Dual Beam Gold-Plated Infra-Red (NDIR).
The transmitter works on 24V AC or DC, 3 wire and gives 4-20 mA output, which can be connected to any PLC, SCADA or MSR Germany PolyGard range of gas controllers such as MGC-03-02-02.
For cellars, pubs, laboratories or CO2 cylinder storage areas, the MSR MGC-03-02-02 gas controller is well designed and includes features such as:
- 2 x alarms LEDs
- 1 x power ON green LED
- 1 x fault LED with auto-diagnostics watchdog
- Built in buzzer
