CO2RT-R
CO2 Sensor
Product #: 99315
Item #: 994078
Rev Date: 2018-07-09
CO2RT-R is a room sensor for measuring carbon dioxide levels in air.
They have a built-in relay with switching output.
Fantech’s CO2RT-R is a patented auto calibration process sets new
standards in CO
2
measuring for HVAC applications. In the same casing,
the CO2RT-R combines measuring of CO
2
-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.
When the CO
2
level goes above the set point the unit will go into high
speed.
Features
• Built-in relay
• CO
2
-level 0...2000 ppm
• Excellent long term stability
• Snap-in cover
Measuring principle
The CO
2
-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
Automatic calibration
CO2RT-R is calibrated automatically, which means that manual
recalibration is not required during the lifetime of the sensor.
Applications
The CO
2
-level gives a direct indication of the indoor air quality. With this
basic information, the ventilation can be controlled with high precision
and the air quality improved. At the same time, the supply air will only be
increased when necessary and the energy costs will thereby be reduced.
