4 in 1 Probe Measures CO2, Humidity, Temperature and Pressure

For Harsh Environmental Conditions

The CO₂ measurement is based on the pollution-resistant E+E dual wavelength NDIR measuring principle. It automatically compensates for aging effects, which leads to outstanding long-term stability. Thanks to the E+E proprietary coating, the humidity sensing element is suitable even for aggressive and corrosive environment. The robust IP65 stainless steel or polycarbonate enclosure as well as various filter caps optimally protect the sensing module from contamination. The probe is therefore particularly suitable for use in agriculture, for example in life stock barns, hatchers, incubators and green houses.

High Measuring Accuracy

The multi-point CO₂ and temperature factory adjustment ensures high accuracy over the entire working range of -40…60 °C (-40…140 °F). Due to the active pressure and temperature compensation with on-board sensors, the EE872 offers a particularly high CO₂ measuring accuracy, independent of altitude or environmental conditions.

Heated Probe Version for High Humidity

The heated version of the EE872 can be used especially for CO₂ measurement in high humidity or condensing conditions. The heating prevents condensation on the sensing module, which makes the probe work reliably even in the high humidity range. Additionally to CO₂ and pressure, the heated version provides the dew point temperature.

Easy Service and Configuration

The EE872 has a modular design. The pluggable sensing module can be replaced in just a few seconds without requiring any tools. Also the filter caps (PTFE or catalytic for H₂O₂ sterilization) can be quickly replaced if necessary.

Configuration and adjustment of the EE872 can be easily performed with the free configuration software together with an optional adapter cable.

Analog or with RS485 interface

The CO₂ measured data is available simultaneously on the analogue voltage and current outputs. Depending on the version, the EE872 with RS485 interface also provides the data for relative humidity (RH), temperature (T), pressure (p) or dew point (Td).
