Modular Probe for CO 2, Humidity, Temperature and Ambient Pressure EE872
v1.8 / Modification rights reserved | 2 EE872 Modular Probe for CO2, Humidity, Temperature and Ambient Pressure The EE872 probe, with a measurement range up to 5 % CO 2 (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 CO 2 and temperature adjustment procedure leads to excellent CO 2 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 CO 2 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 CO 2 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 H 2O2 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 or BACnet MS/TP protocol 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.

v1.8 / Modification rights reserved | 4 The E+E proprietary sensor coating is a protective layer applied to the active surface of the sensing element. The coating substantially extends sensor lifetime and ensures optimal measurement performance in corrosive environment (salts, off- shore applications). Additionally, it improves the sensors’ long term stability in dusty, dirty or oily applications by preventing stray impedance caused by deposits on the active sensor surface. Protective Sensor Coating 136 (5.35) M12x1 plug 65 (2.56) Ø25 (0.98) 61 (2.4) Filter Values in mm (inch) Dimensions Sigma 05 with EE872 The EE872 is compatible with the Sigma 05 host device of the E+E Modular Sensor Platform. Together they become a versatile, plug-and-play CO 2/RH/T/p modular sensor with analogue outputs and optional display. Besides EE872, Sigma 05 accommodates also other E+E intelligent sensing probes. See www.epluse.com/sigma05 for further details. E+E Modular Sensor Platform If the probe remains on the measuring site during cleaning operations, the optional calibration adapter can be used for protection. For this purpose, both nipples are closed with the rubber caps supplied. In case the probe is removed from the site, it is recommended to apply the protection caps for the M12 cable socket and the EE872 M12 plug. Device Protection During Site Cleaning
