Operating Instructions
This thermohygrometer operates mechanically and continuously displays the current temperature and humidity without any user input or power source.
- Temperature Reading: The larger needle indicates the temperature in both Celsius (°C) and Fahrenheit (°F).
- Humidity Reading: The smaller needle indicates the relative humidity in percentage (%).
Allow the device approximately 30 minutes to stabilize after placement to provide accurate readings for its new environment.

Troubleshooting
If you encounter issues with your thermohygrometer, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Improper placement (direct sunlight, drafts, heat sources) | Relocate the device to a stable environment away from extreme conditions. Allow 30 minutes for stabilization. |
| Needles not moving | Device is in a very stable environment with no changes in temperature/humidity; internal mechanism damage | Move the device to an area with known temperature/humidity fluctuations to test. If still unresponsive, the device may be damaged. |
| Physical damage (cracked glass, bent needles) | Impact or mishandling | The device is not user-repairable. Consider replacement. |
