But if the device has approximately 20 ° C operating temperature of heating are the results nearly correct)
For comparative measurements to detect thermal bridges in order to, for example, finding accommodation to assess the quality of buildings can however, it is always a very good resource. I bought it just for this purpose and this purpose fulfilled it perfectly. In combination with a humidity indicator (eg. Trotec BM30) can very quickly draw conclusions, if one could possibly give it the promise of a new home mold problem or not. To check our terrariums (sun places the residents measure), or even to assess their body temperature but it is also well suited. Who wants to know under what conditions the results are accurate should make some comparison measurements with a good old mercury thermometers.
From my perspective for the amateur craftsmen or home seekers highly recommended. Who needs should exact values, as with any other measure also lead an objective error analysis in the field. Digital readings entice unfortunately very easy to you to believe. However, even very expensive measuring instruments are still attached tables for correction values :-)
In this sense, absolute buy recommendation!
