User Manual EE1900 Humidity Module for Climate Chambers
1.2.3 Intended Use
The EE1900 humidity module is optimised for the measurement of relative humidity (RH) and dew point
temperature (Td) in climate chambers. The use of the EE1900 other than described in this manual is
not allowed.
The manufacturer cannot be held responsible for damages as a result of incorrect handling, installation
and maintenance of the device.
Unauthorized modifications of the product lead to loss of all warranty claims. The device may only be
powered with separated extra-low voltage (SELV).
Disclaimer
The manufacturer or his authorized agent can only be held liable in case of willful or gross negligence.
In any case, the scope of liability is limited to the corresponding amount of the order issued to the

For disposal, the individual components of the device must be separated according to local recycling
regulations. The electronics shall be disposed of correctly as electronics waste.
1.4 ESD Protection
The sensing elements and the electronics board are ESD (electrostatic discharge) sensitive
components of the device and must be handled as such. The failure to do so may damage the device
by electrostatic discharges when touching exposed sensitive components.
1.5 Scope of Supply
• EE1900 according to ordering guide
• Inspection certificate according to DIN EN 10204-3.1
2 Product Description
2.1 General
The sensing probe and the electronics of the EE1900 undergo the factory adjustment together and may
not be separated from each other. Do not cut, shorten or extend the probe cable.
The analogue output of EE1900 can be set to voltage or current with a slide switche on the electronics
The RH output is preferred for applications with rather uniform temperature distribution, while the Td
output is advisable in case of large T gradients in the environment.
