Belimo Americas has released the new dual channel CO2/temperature sensors with an increased range to 5000 ppm. The dual channel technology measures two-wave lengths split from a single light source. The sensor automatically takes a reading using the reference channel. Any change in the measurement indicates a change in the optics of the sensor. The sensors automatically adjust the CO2 measurement when a change is detected to prevent drift. Manual calibration is not needed. The company says high accuracy is maintained even in busy applications such as retail stores or hospitals.
The CO2/temperature sensors are available in degrees Fahrenheit (model 22DTC-5105) or Celsius (model 22DTC-1105). The dual channel sensors are ideal for applications requiring 24/7 hours of operation such as hospitals, retail stores, manufacturing, and indoor farming.
