Regin’s CO2RT series with patented auto calibration process sets new standards in CO2 measuring for HVAC applications. In the same casing, the CO2RT series combines measuring of CO2-level, temperature and optional relative humidity. The sensor is mounted in the cover-part of the casing. The cover is easy to detach from the back by means of snap-in grips and detachable terminals. This makes mounting easier. Furthermore, no cables have to be disconnected,
which simplifies service and replacement.

Measuring principle
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)
