Miniature Hygrometer TFA

Very small low-cost hygrometer in neutral design, with fold-away stand, also suitable for wall mounting. The device displays simultaneously the actual temperature and relative humidity.

Accuracy is reasonable in relation to its low price (initially ±5% RH, mostly much better) but don't expect accuracy to last for years. You should cross-check it regularly with a calibrated hygrometer. The instrument can not be calibrated. If accuracy drifts outside specifications, you have to dispose it or you write the drift on the instrument, like "values 3% RH too high".

Other functions:

  • automatic determination of Max/Min
  • values reset-function for Max/Min values
  • low battery indication

Battery life is about 12 month, with high quality batteries (Varta, Sony...) even more.
