Hygrometers & Thermo-Hygrometers – Reliable measurement of humidity & temperature
A stable indoor climate protects health, furniture, and the building structure. With our hygrometers and thermo-hygrometers, you can keep track of humidity and temperature – from the living room and bedroom to the cellar and workshop. This helps prevent mold, ensures targeted ventilation, and increases living comfort.
Why a Hygrometer is Essential
Healthy indoor climate
The optimal relative humidity is typically in the range of 40–60 %. Hygrometers show trends and peaks – ideal for timely ventilation or humidification.
Prevent mold
Excessive moisture promotes mold – especially in cold corners and basements. Models with mold alarm or room climate indicator make risks visible and provide clear guidance.
Save energy
By ventilating purposefully, rather than "on a hunch", heat loss is avoided. Some devices provide a ventilation recommendation – practical in everyday life and good for your wallet.
How to Choose the Right Thermo-Hygrometer
- Usage location: Bedroom, living room, children's room, kitchen, or cellar – one device per room gives the most accurate results.
- Display & comfort: From compact & simple to large displays with room climate smiley, max/min alarm, and humidity history.
- Indoor vs. indoor/outdoor: For balconies, garden sheds, or greenhouses, a set with an outdoor sensor is worthwhile.
- Warning functions: Mold alarm and heat warning are especially useful in old buildings, bathrooms, and kitchens.
Tips for Correct Measurement & Placement
- Place the device at eye level or hang it on an interior wall – avoid direct placement near windows, heating, or in direct sunlight.
- Ventilate after showering/cooking and allow the readings to stabilize for 10–15 minutes.
- For realistic readings, maintain a 20–30 cm distance from exterior walls and avoid drafts.
FAQ: Hygrometers & Thermo-Hygrometers
What is the difference between a hygrometer and a thermo-hygrometer?
A hygrometer measures the relative humidity. A thermo-hygrometer additionally records the temperature – this helps identify correlations (e.g., cold air + high humidity = higher mold risk).
What values are ideal to avoid mold?
A practical target range is about 40–60 % r. H. and comfortable room temperatures. Short-term fluctuations are normal – trends are important. If the humidity remains too high, ventilate more often or dehumidify.
Where is the best place to set up a hygrometer?
On an interior wall, at eye level, with some distance from windows, exterior corners, heaters, and direct sunlight. In problem areas (bathroom/cellar), a second device for cross-checking is worthwhile.
Indoor/outdoor sensor – when is it useful?
If you want to monitor the outdoor values as well (e.g., for ventilation or for the garden shed or greenhouse). Tip: Check out our indoor/outdoor thermometers.
Do I need a mold alarm or a ventilation recommendation?
If you want clear action signals, these features are ideal: A mold alarm warns of critical combinations, and the ventilation recommendation helps you ventilate at the right time.
How do I permanently prevent mold?
Regularly monitor, ventilate properly, reduce moisture sources (e.g., drying laundry), avoid significantly lowering room temperatures, and keep an eye on problem areas. A thermo-hygrometer helps establish routines.
