immediately, which usually takes a few minutes. 2. After starting the
machine, the temperature displays ℃ and needs to be switched to ℉ by
pressing the on button. 3. This instrument is suitable for household air
detection with slightly lower accuracy. If you need a more accurate
instrument, please choose another one.
