CO2 sensor module with heating function EE872
CO2 measurement is possible even in agricultural applications where there is a possibility of moisture dispersion.
● Prevention of condensation through sensor heating function ● CO2 measurement principle: two-wavelength non-dispersive infrared method (NDIR), with automatic calibration function ● Measures CO2, relative humidity (RH), temperature, and pressure (p) ● Analog output or BACnet MS/TP or Modbus RTU ● Maximum CO2 measurement range of 5% (50,000 ppm) ■ The EE872 is equipped with a heating function, demonstrating high reliability even in harsh and condensation-prone environments. Its IP65 housing and replaceable filter provide excellent protection in contaminated environments. If a H2O2 catalyst filter is selected, it can also be used for applications involving sterilization with H2O2. ■ The automatic calibration function allows for accurate CO2 measurements regardless of temperature, altitude, or weather conditions.
