My comparison of the six months old and the newly delivered:
- Temperature difference of 0.4-0.5 ° C on both devices
- Humidity difference of 3% (48% to 51%)
More I asked a several years old digital thermometer next:
- Old TFA 30.5002: 23.8 ° C
- New TFA 30.5002: 24.3 ° C
- Ancient digital thermometer: 24.0 ° C
According to the manual, a tolerance of + - 1 ° C and + in there - 5% humidity.
Since I have judged my old TFA personally very accurate it was important to me that the deviation from it is not too high.
The small difference between the two devices as well as the TFA slight deviation to the old digital thermometer from a different manufacturer, I find very satisfactory.
Otherwise is optically very noble, it has a large clear display. Temperature and humidity have one line and are in very big fat font. The viewing angle is perfect, even if one is inclined next to it can be read very well and of course thanks to the large font also from a greater distance. In my eyes, the hierige TFA 30.5002 with the best and most beautiful thermometers for home use.
Of course, the measuring instruments are not 100% accuracy in this price range, but for home use, the measured values are very realistic and satisfactory.
Small tolerances well within the equipment are in order. For all buying the thermo-hygrometer: Comparing it where you certainly since that vote the values with other devices and compares it with your personal preferences. If the deviations are too large, which may well happen, it is best to simply exchanged. But deviations of 0.5 + - ° C are quite in it and in my opinion this is the measure of tolerance. 1 ° C tolerance I think too much, I would have sent it back but the 0.4-0.5 ° C are properly.
A battery is supplied with the product, in other words you need it just unpacking, open the battery compartment and insert the battery, ready!
Very important: The unit needs a few hours until the measurements are real. Therefore, do not be frightened if the readings at the beginning are not equal right. Unfortunately, the device is eetwas sluggish, which means it regulates itself very slowly in 0.1 steps to the real value Ran. For me it just lags that the package was in a hot car and was accordingly warm.
Therefore, if you buy it you let the device best at least 1 day to run an opinion on the accuracy of form.
If the measurement inaccuracies still be too high, a conversion is advisable.
Otherwise, for me personally with the best thermo-hygrometer, it would buy again at any time.
