Cleaning: Use a soft cloth to clean the surface of the hygrometer. Avoid harsh cleaning agents that may damage the material.

Storage: Store the hygrometer in a cool, dry place when not in use. Keep it out of direct sunlight to prevent damage from heat or UV rays.

• Calibration: Regularly check the accuracy of the hygrometer and, if necessary, carry out a calibration according to the instructions in the manual.

• Preventing corrosion: If you use the hygrometer outdoors, ensure that the housing does not come into contact with water or high humidity for extended periods of time to prevent rust formation.

• How does the Fischer Hair Hygrometer work? The Fischer 111 uses specially treated human hair that expands or contracts depending on the humidity. This ensures that the hygrometer responds quickly and accurately to changes in humidity.

Can I use this hygrometer both indoors and outdoors? Yes, the Fischer Hair Hygrometer is suitable for both indoor and outdoor use, provided the temperature is within the range of -35°C to +65°C.

How often should I calibrate the hygrometer? It is recommended to check and calibrate the hygrometer periodically for optimal accuracy. This depends on the conditions of use, but an annual check is usually sufficient.

Is the Fischer 111 hygrometer corrosion-resistant? The hygrometer is made of stainless steel or powder-coated steel, which helps prevent corrosion. Make sure you maintain it properly, especially when using it outdoors.

• What is the accuracy of the Fischer Hair Hygrometer? The hygrometer has an accuracy of ±3% RH (20-100%), with a scale deviation of +1 division. This makes it a reliable choice for precise humidity measurements.
