In the manufacturing process, further processing, storage and transport, the exact determination of moisture and temperature becomes increasingly important. Only an accurate moisture monitoring can guarantee high product quality.

The LF-TD-U transmitters of Schaller measurement instrumentation, with its robust and easy to mount aluminium housing, are best suited for all applications in this field. A sensor tube of 102mm length (Ø 12mm) enlargens the application potential of the LF-TD-U humidity and temperature transmitter.

The USB port allows a easy connection to any PC.

The used capacitive moisture sensor ensures long-time stable and accurate measuring values and is resistant to normal pollution and a lot of chemicals. Furthermore, the sensors used in the LF-TD transmitters are characterised by rapid conditioning.  

The excellent measuring accuracy of the LF-TD series is guaranteed by a factory-calibration at six humidity points. On request a calibration certificate can be provided.
