The Dwyer CDWP Series carbon dioxide transmitter features a non-dispersive infrared CO2 sensor with universal outputs in an industrial housing. The single beam dual-wavelength NDIR sensor eliminates light source aging effects which increases sensor life and accuracy. This sensing technology provides this Dwyer CO2 transmitter with highest level of accuracy compared to Automatic Baseline Correction (ABC) methods, which can unintentionally shift the calibration based on CO2 levels and barometric pressure conditions.
The IP54 aluminum housing of the Dwyer CDWP Series carbon dioxide transmitter features a gray finish which is designed to withstand a 168 hour salt spray test. Common applications for the Dwyer CDWP include animal husbandry, mechanical rooms, CO2 refrigeration monitoring and greenhouses.
