All outdoor thermometers are susceptible to this condition. You can be confident that Tel-Tru thermometers are designed for continuous accuracy and longevity during potential condensation cycles.
As with any outdoor device subjected to changing weather conditions, condensation may form on the inside of the lens of a thermometer when the temperature of the lens is at or below the dew point temperature of the air surrounding the unit. The amount of condensation depends on the level of humidity or water vapor in the air that is trapped inside the thermometer. Water vapor may begin to condense to the liquid phase when cooled. Warm moist air can accelerate the conditions of condensation formation being a byproduct of the cooking process.
The moisture may be removed by putting the thermometer in the sun, or inside a warm, dry environment. Placing the thermometer in a 170°F oven may aid in dissipating condensation.
If you believe that this is not the issue and you have a defective thermometer, please send us a picture of the thermometer with the issue again with the pin stamp on the side of the case to customerservice@teltru.com.
