This thermo-hygrometer allows for quick and uncomplicated monitoring of a healthy indoor climate, thanks to its clear display and simple operation, making it ideal for living and sleeping areas, offices, training rooms, and meeting rooms.
Hair hygrometers, like this model, are characterized by their high precision. Equipped with a high-quality measuring mechanism 'Made in Germany', it ensures a measurement accuracy of ± 3 % r.H. in the range of 20 to 100 % relative humidity. The measuring principle is based on the length change of a specially treated synthetic fiber, which expands in moisture and contracts in dryness. This length change is converted into a rotational movement that controls the pointers on the display. The display of the hygrometer can be adjusted and calibrated through a simple zero point correction.
Ventilation recommendations
The display shows two scales with ventilation recommendations. During the cold season, the room humidity should not exceed 60%, while in summer, a slightly higher humidity of up to 70% in living areas is considered normal. Cooler basements, on the other hand, should not have more than 60% humidity year-round to avoid mold and odor formation. If the humidity remains above the suggested values despite ventilation, the use of a dehumidifier should be considered.
Hanging on the wall
This device is designed to be mounted on a wall. For this purpose, a suitable hole for a nail or screw is incorporated into the housing on the back. To ensure that humidity and temperature values are measured as accurately as possible, large air slots are provided on the sides. These allow for the free flow of room air and thus the best possible measurement. Please note that cold or poorly insulated exterior walls can distort the value. Therefore, optimal placement with reliable measurement values is on walls inside the building.
Recalibration
After transport, it may happen that the mechanical settings are altered due to vibrations. Additionally, accuracy may deteriorate if the thermo-hygrometer has been stored in a very dry environment for a long time. In this case, the humidity display can be easily corrected using a small screwdriver on the side adjustment screw. The temperature screw is accessible from the back of the housing (bottom hole). For calibrating temperature and humidity, it is easiest to use another thermo-hygrometer that you consider reliable for the values. Please note when adjusting by hand that warm, moist hands can also change the displayed values, just like breath.
