CO2RT-R-D Transmitter
Art. no.: 6993
Measuring system CO2-sensor
The CO2-concentration is measured by means of infrared light, a technique that measures the absorption in gases. It has a reference measuring system that compensates values in relation to changes in light intensity. The method gives several advantages:
• Very high accuracy
• Exact identification of the detected gas
• Low risk for contamination
• Short response time
• High long term stability
• Long calibration interval (>5 years)
Display
The display models have an LCD-display showing actual values in an alternated series.
Applications
Measuring the CO2-level gives a direct indication about the indoor air quality. With this basic information ventilation can be controlled with high precision and air quality improved. At the same time supply air will only be increased when it is necessary thus cutting energy costs.
