How to use
Mount the thermometer-hygrometer at an appropriate height on a sauna wall, away from direct contact with steam or heating elements, so it measures air conditions representative of the cabin atmosphere.

Periodically check the instrument for correct placement and clear visibility of the dial.

Install the unit on an interior sauna wall at eye level, away from direct steam flow and the stove, to ensure accurate readings. Avoid placing the device in direct contact with water or on surfaces that exceed recommended mounting temperatures.
