The MostraLog is a battery-powered precision data logger for long-term recording of relative humidity and air temperature. The outstanding features are the above-average measuring accuracy and the long service life of the measuring device. The housing is both beautifully designed and functional, offering protection against opportunistic theft.

Protecting objects such as valuable paintings or instruments from excessive or low humidity and temperature requires continuous and reliable monitoring of these parameters. The MostraLog displays values on a large LCD screen and also records them on an SD card.

It is operated either manually via the built-in pushbutton or conveniently via IR remote control.


The housing is made of low outgassing plastic—ensuring that objects to be monitored are not affected. Thanks to an external sensor, the MostraLog can also be installed up to 2.5 m away from the object being monitored. If preconfigured limit values are exceeded or not reached, a higher-level warning system is triggered.

The measuring device can be easily attached to surfaces using two screws. Both the device and the SD card are protected against theft by being mounted on the wall and by an integrated security mechanism.

Thanks to an intelligent calibration mode, measurement inaccuracies due to aging can be recalibrated.
