Note
All visual IR thermometers need sufficient warm-up time for the most accurate temperature measurements. This time can often vary by model and by environmental conditions. Although most visual IR thermometers are fully warmed up in 3 to 5 minutes, it is always best to wait a minimum of 10 minutes if the most accurate temperature measurement is very important to your application. When you move a visual IR thermometer between environments with large differences in ambient temperature, more adjustment time can be required.
