Infrared Sensor
A Time-Tested Technology to Provide Precise CO2 Control

Caron's CO2 Incubators utilize a single beam, dual-wavelength IR CO2 Sensor to get the most accurate measurement of CO2 in the incubator. It is the leading, proven technology in the field of CO2 measurements. The IR Sensor offers unmatched precise control and stability over wide temperature and relative humidity ranges.

It is silicon based, which contributes to the durability and a long life, because water vapor, dust and most chemicals do not affect the sensor's measurements. IR Sensors withstand these harsh environments that are inherent in demanding applications. IR technology is ultra stable, regardless of door openings, and quickly recovers CO2 to the setpoint once the door is closed.

This graph shows a typical CO2 response to a 30 second door opening.
 
Comparison of Caron's IR Sensor vs. Conventional TC Sensors

 
Caron's IR Sensor
TC Sensor
Accuracy
The Sensor is not affected by temperature or humidity; it solely reads CO2 levels.
Temperature and humidity influence the CO2 reading; measures the thermal conductivity of air, not CO2 alone.
Recovery
CO2 recovers in less than five minutes after a 30 second door opening.
CO2 cannot recover until both temperature and humidity stabilize; the average CO2 recovery is 30 minutes after a 30 second door opening.
Reliability
Gives precise readings of CO2 levels at all times because the sensor is only
measuring CO2.
The CO2 display gives false readings until temperature, humidity and CO2 are
completely stable.
Convenience
You can change CO2, temperature and humidity settings without having to re-calibrate the
IR Sensor.
Sensor calibration is required each time you change any of the settings; weekly calibration is
typical with these sensors
