## Long description

Manufactured in Germany, the thermometer includes a two-point adjustment for improved accuracy and stable readings. The coloured, non-mercury filling ensures compliance with modern safety and environmental standards while maintaining good visibility of the measured value. Its slim plastic housing and clear degree markings make installation and reading practical in compact spaces.

How to use
Select a location away from direct heat sources, radiators or sunlight to obtain representative ambient temperature readings.

Store or install the thermometer within its specified temperature range to prevent damage to the housing and liquid column.
