If you need a thermometer that can switch between Celsius and Fahrenheit, consider our Circular Thermometer Hygrometer.) The device is rated for use in ambient temperatures from -10°C to 60°C, but the display operates reliably only between -5°C and 50°C. Using the device outside this display temperature range may cause slow response, screen lag, or other visual anomalies. Avoid prolonged use or storage in extreme temperatures. Extended exposure to -10°C or below may cause moisture-sensitive components to freeze and sustain permanent damage. Similarly, continuous operation at 60°C or above can lead to gradual screen dimming, eventual blackouts, and potential damage to heat-sensitive parts. For optimal performance and longevity, avoid prolonged use in extreme temperatures.
