The EE872 from E+E Elektronik measures the CO2 concentration up to 5% (50 000 ppm) as well as relative humidity, temperature, and ambient pressure. Additionally, the 4-in-1 probe also calculates the dew point temperature.

It is perfectly suited for use in a harsh and aggressive environments, such as agricultural applications. The active pressure and temperature compensation ensure a very high CO2 measuring accuracy. A heated probe version is available for CO2 measurement in high-humidity applications.

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. Due to the E+E proprietary coating, the humidity sensing element is suitable even for aggressive and corrosive environments.

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 greenhouses.

High Measuring Accuracy

EE872 offers a particularly high CO2 measuring accuracy, independent of environmental conditions

The multi-point CO2 and temperature factory adjustment ensure high accuracy over the entire working range of -40...60 °C (-40…140 °F).

Due to the active pressure and temperature compensation with onboard 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. In addition to CO2 and pressure, the heated version provides the dew point temperature.

Easy Service and Configuration

The pluggable sensing module can be replaced in just a few seconds without requiring any tools

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 analog 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).
