The EE1950 dew point measurement module from E+E Elektronik is dedicated for OEM applications with continuous high humidity and condensing conditions, such as climate and test chambers. Excellent temperature compensation ensures high accuracy over the entire working range from -70 °C to 180 °C (-94 °F to 356 °F). The device is also particularly resistant to pollutants and corrosive agents.

Optimized for High-Humidity Conditions

The EE1950 employs the innovative, heated E+E humidity and temperature sensing element HMC01, which shows best long-term stability even at continuous high relative humidity. Besides, the proprietary E+E coating protects the sensing element from dust, dirt and corrosion. This improves significantly the measurement performance in harsh environment.

Precise Calculation of Relative Humidity

Together with an additional, external temperature sensor, the EE1950 allows for precise calculation of the relative humidity. It is therefore a perfect solution for climatic chamber control.

High Resistance to Chemical Contamination

Thanks to the Automatic Sensor Recovery (ARC) function, the sensor copes well with chemical contamination. By controlled heating, the chemicals gaze out from the sensing element, which improves the long-term stability and service life of the device. The ARC mode can be triggered either via a push button on the board or an electrical signal.

User-Friendly Configuration and Adjustment

The dew point measured data is available on the analogue output, which can be set to current or voltage with a slide switch. The output scaling and adjustment can be easily performed via the service interface and the free EE-PCS configuration software.

Easy Design-In

The choice of two board sizes (55 x 46.5 mm / 2.17 x 1.83 ʺ or 90 x 70 mm / 3.54 x 2.36 ʺ) and the high-quality, flexible probe cable facilitate the design-in of the EE1950. The stainless steel probe is available in 65 mm (2.56 ʺ) and 200 mm (7.84 ʺ) length.
