Digital Thermo-Hygrometer TFA, black

Very small, handy thermo-hygrometer with a neutral design, very suitable for roughly checking the showcase climate. The practical magnetic holder can be used as a stand or easily attached to many surfaces using the adhesive pad. Despite the very low price, the accuracy is not bad at all (initial accuracy approx. ±5% RH).

Successor product for the TFA miniature hygrometer.

The device cannot be calibrated, i.e. the accuracy should be checked from time to time with an accurate hygrometer. If the accuracy is outside the measurement error, the drift can at best be noted on the device (e.g. "shows approx. 3% RH too low"). The sensors are of course not as accurate and not as stable over the long term as higher quality devices.
