NDIR CO2 sensor EE872

Modbus RTU0-10 V4-20 mA

Modular Probe for CO2, Humidity, Temperature and Ambient Pressure The EE872 probe, with a measurement range up to 5 % CO2 (50 000 ppm), is suitable for use in harsh and demanding environment in agriculture, life stock barns, hatchers, incubators, green houses or outdoors. Outstanding Accuracy A multi-point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire T working range of -40…+60 °C (-40…+140 °F), which is ideal for agriculture or outdoor use. Long-Term Stability EE872 incorporates the E+E dual wavelength NDIR CO2 sensor, which automatically compensates for ageing effects and is highly insensitive to pollution. The RH sensing element with E+E proprietary coating is suitable even for aggressive and corrosive environment. Pressure and Temperature Compensation The active compensation with on-board sensors leads to best CO2 measurement accuracy independently of weather conditions, altitude or temperature. 4 in 1 Beside CO2, the EE872 measures also relative humidity (RH), temperature (T) and ambient pressure (p). Additionally, the device calculates the dew point temperature (Td). Reliable in Harsh and Condensing Environment The heated version of EE872 is suitable for high humidity and condensing environment. The IP65 enclosure and the replaceable filter offer excellent protection in polluted environment. With a special filter, the EE872 is also appropriate for applications with periodical H2O2 sterilization. Analogue Output or RS485 Interface The CO2 measured data is available simultaneously on the analogue voltage and current outputs. Depending on the model, EE872 with RS485 interface with Modbus RTU also provides the values for RH, T, p and Td. Configurable and Adjustable The free PCS10 Product Configuration Software together with an optional adapter cable facilitates the configuration and adjustment of the EE872.
