3. Setup
The BALDR Floating Pool Thermometer is designed for simple, hassle-free setup.
- Initial Charge: Upon receiving the thermometer, place it in a location with sufficient daylight for a few hours to allow the solar panel to charge the internal battery. If the display is not showing numbers, it may need more time to charge.
- Placement: Once charged, simply place the solar pool thermometer into the water body you wish to monitor. It will float on the surface.
- Temperature Unit Selection: To switch between Fahrenheit (°F) and Celsius (°C), locate the small button on the underside of the thermometer (often labeled F/C). Press this button to toggle the display unit.

4. Operating Instructions
Using your BALDR Floating Pool Thermometer is straightforward:
- Automatic Operation: The thermometer continuously measures and displays the water temperature as long as it is in the water and exposed to light for charging.
- Reading Temperature: The digital display will show the current water temperature. Ensure the display is facing upwards for optimal readability.
- Solar Charging: For continuous operation, ensure the thermometer's solar panel is exposed to sunlight. The device will automatically recharge its internal battery.

5. Maintenance
To ensure the longevity and accuracy of your thermometer, follow these maintenance guidelines:
- Cleaning: Periodically clean the thermometer's surface, especially the solar panel and display screen, with a soft, damp cloth to remove any dirt, debris, or mineral buildup. Avoid abrasive cleaners.
- Storage: During off-season or extended periods of non-use, store the thermometer in a cool, dry place away from direct sunlight. Ensure it is clean and dry before storage.
- Water Exposure: While IPX8 waterproof, prolonged exposure to extreme chemicals or highly corrosive water may affect its lifespan.
- Sensor Protection: Avoid physical impact to the sensor probe located at the bottom of the device to maintain accuracy.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Insufficient solar charge. | Place the thermometer in direct sunlight for several hours to allow the internal battery to charge. |
| Inaccurate temperature reading. | Sensor probe is dirty or damaged; device not fully submerged. | Clean the sensor probe. Ensure the thermometer is floating freely and the probe is fully immersed in the water. Compare with another reliable thermometer. |
| Screen fogging. | Humidity or condensation inside the display. | The built-in desiccant should manage this. If persistent, ensure the device is not exposed to extreme temperature fluctuations. |
| Device not floating correctly. | Obstruction or damage. | Check for any debris or damage that might affect its buoyancy. |
