- Reading Temperature: The black needle on the dial indicates the current temperature in degrees Celsius (°C).
- Measurement Range: The thermometer measures temperatures within a range of -35 °C to 55 °C.
- Accuracy: The measurement precision is approximately +/- 1 °C.
- Graduation: The dial is marked with 1-degree increments for clear readings.
6. Maintenance
Maintaining your Fischer thermometer is simple and ensures its longevity and accuracy.
- Cleaning: To clean the thermometer, simply wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the stainless steel finish or the dial.
- Storage: If storing the thermometer for an extended period, keep it in a dry place away from extreme temperatures and direct sunlight.
7. Troubleshooting
If you encounter issues with your thermometer, consider the following:
- Inaccurate Readings: If you suspect inaccurate readings, verify that the thermometer is not placed in direct sunlight, near a heat source, or in a drafty area. Relocate it to a more stable environment and allow time for stabilization.
- No Movement: Ensure the thermometer is not obstructed. If the needle remains static, gently tap the casing. If the issue persists, the internal mechanism may be damaged.
