Space CO2 Sensors and Controllers | HDH-N HDH Room CO2 and Temp Transmitter with Display

HDH room transmitters measure CO2 content and temperature in wide range of applications. The transmitters use the unique ABCLogic™ measurement technology that automatically resets the zero point (calibrates the CO2 detector).

The transmitters have temperature measurement outputs as standard, and humidity measurement can be offered as an option. Industry standard 0..10Vdc outputs guarantee integration to most applications. The transmitters are available with display (-N models) or without display. These CO2 transmitters can also accommodate built-in controller option making them most advanced solution for accurate ventilation control.

ABCLogic is a result of over 15 years R&D for the CO2 measurement. ABCLogic measures the background CO2 level and uses the advanced statistical analysis to correct the readings automatically, removing the need for expensive calibration.
