I wanted a simple thermometer for Them temperature gauge in the freezer and exactly what I got with this thermometer well. The small scale makes reading precisely, however a real challenge! Taking the thermometer but from the freezer compartment the reading by the large difference in temperature is very fast very inaccurate. To determine the exact temperature so do not, however, well suited to detect a temperature range. I have a simple subdivided freezer. The lattice grid divides the freezer compartment at a height of about 20cm. After the Themometer slipped through the grate broke it by the impact and the glass tube was unusable.
All in all you can not publishers of quality for the price probably. The mission went very quickly and took place in a sufficiently protected packaging.
