Have I not bought at Amazon, the PTD 1. The part of measures on the one hand without contact, the surface temperature and displays it exactly right on the display. But you should have defined the material in advance what is actually very simple. There are three possible settings for this. Should be manageable by any ... Additionally, there is an additional temperature sensor for the ambient temperature and a further sensor for rel. Humidity of the ambient air. These two things can then calculate how detect temperature differences of ambient air and the object to be measured and thus heat or cold bridges. Genial is the ability to make hypothetical seats in the house find suitable for the production of molds. For this purpose, on the basis of ambient temperature and relative humidity. Humidity, the dew point is calculated and then this 'compared' with the measured surface temperatures and identify places in the house with a red LED on suitable. You can also reverse this and take preventive measures and thus prevent mold. All in all a useful instrument with which the own suspicions are confirmed. Temperature measurement, incidentally, also worked very well. To this end, simply put on temperature measurement, select the material to the center position and open his mouth set, breathe and objectives into the pharynx. Takes a brief second and provides very accurate values. At other body openings I have not tried it and I will not either. Strong buy recommendation!
