Heated Humidity and Temperature Probe for Meteorology

The EE260 humidity and temperature probe with heated humidity sensing element and probe heating delivers precise and reliable measuring results even at high humidity conditions.

Measuring Performance

The EE260 humidity and temperature probe has a dual heating system (sensing element and probe heating). This prevents condensation on the RH sensing element, the sensing head and the filter cap. The probe therefore provides precise and reliable measurement results even in the case of permanent high humidity.

Another benefit of the dual heating system is the very short response time and a fast recovery after condensation.

The E+E sensor coating improves the long-term stability and service life in dusty and corrosive environments.

Compact and Robust

The innovative enclosure of the EE260 combines a heated humidity sensing head and an additional temperature sensing element in a single probe.

Due to its compact design, the probe is compatible with commercially available rotationally symmetric sensor radiation shields.

The robust IP67 enclosure made of UV- and heat-resistant elastomer protects the internal electronics from environmental influences and mechanical damage.

Analogue and Digital

The EE260 probe provides the measured data simultaneously on two freely configurable voltage outputs and via the RS485 interface (Modbus RTU).

Based on the measured humidity and temperature values, the EE260 calculates further humidity-related quantities such as the dew point temperature, absolute humidity or mixing ratio.

Typical Applications

  • Meteorological weather stations
  • Weather warning systems (road traffic, airports)
  • Detection of icing hazard

CO2 sensor for demanding applications

The EE820 measures reliably CO2 concentration in harsh, demanding applications. A multipoint CO2 and temperature factory adjustment leads to excellent accuracy over the entire temperature working range.

The EE820 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. For fast response time requirements there is an EE820 version with forced air circulation created by a fan installed behind the filter.

With its robust, functional IP54 enclosure and a special filter, the EE820 is suitable for polluted applications such as agriculture and livestock barns. The M12 connector facilitates the removal of the device before site cleaning operations. An optional kit allows for easy configuration and adjustment of the EE820.

Typical Applications

  • Greenhouses
  • Fruit and vegetable storage
  • Hatchers and incubators
  • Life stock barns
