Gas Alarm Systems is offering a Self-Calibrating CO2 (carbon dioxide) Monitor which is maintenance free. It features Dual Beam, Gold Plated Infra-Red Detector, Range: 0 - 5% Vol CO2. It has an ABC feature here the micro-computer self calibrates based on background CO2 levels. No need to spend 100s of Dollars for calibration gases.

Gas Alarm Systems Self-Calibrating CO2 Detector / Monitor works on Infra-Red sensing technology. Due to it's ABC feature (Automatic Background Calibration), it self-calibrates itself (built in micro-controller does it) based on background CO2 levels. It is totally maintenance free with expected life of 15 years. The sensing technology is based on Dual Beam Gold-Plated Infra-Red (NDIR) sensing technology.  

The Transmitter works on 24 V AC or DC, 3 wire and gives 4-20 mA output which can be connected to any PLC, SCADA or MSR Germany PolyGard rage of gas controllers like MGC-03-02-02   For Cellars, pubs, laboratories or CO2 cylinder storage areas the MSR MGC-03-02-02 Gas Controller is well designed. It has display, keypad, 2 x alarms LEDs, 1 x power ON green LED, 1 x fault LED with auto-diagnostics watchdog, It has a built in buzzer. There are 2 x relays for external alarms, for controlling ventilation fans or shutting-off gas supply solenoid valves. It works on 24 V DC. Power supply 240 VAC-24 VDC, SMPS is also available.
