Customer Review

The thermo-hygrometer has two displays: temperature and humidity.

The temperature gauge is very accurate and true, the humidity is displayed permanently unfortunately too high. On average, 8 to 18% excess.
Found we have this, as I have borrowed a calibrated unit and this had next asked. Thus, the TFA 30.5005 is unfortunately useless and therefore also only 1 point.
