Review on Discover Hidden Thermal Changes with BLACK+DECKER TLD100 Thermal Detector by Tyler Parker

Unless you just want a rough estimate of temperatures and/or temperature differences, don't worry. It's not very accurate or precise. The purpose of this device is to look for a "reference" temperature and then quickly determine if other things are hot or cold so you can find things like air leaks and the like. When the device is first turned on (by holding it still in a certain place/object), it almost immediately reads a temperature and sets it as the reference temperature. OK Bye. Then, without moving it, the "scanned" temperature will slowly decrease over the next 2-3 seconds. typically around 1-1.5 degrees Fahrenheit. It's almost like using a completely different sensor. Turning it off and on again just repeats the same cycle. The reference temperature is always approximately the same for a given object, and after a few seconds the scanned temperature is slightly lower. A feature of it is the color it displays based on the scanned temperature versus the reference temperature. green or red depending on whether the measured temperature is lower, about the same, or higher than the reference temperature. Has 3 sensitivity settings. most sensitive is 1 degree Fahrenheit, then 5 degrees Fahrenheit, then 10 degrees Fahrenheit. But since the scanned temperature drops immediately from the reference temperature, the most sensitive setting (1 degree Fahrenheit) is practically useless - the reference object is immediately scanned as "blue". I found this in the accuracy manual: accuracy at 5.9" (150mm) ±5°F (2.8°C) at 32°F (0°C) ±2.5°F (1.3°C) ) at 73 °F (23 °C). ) ±2.2 °C (4 °F) at 100 °C (212 °F). So yeah, by no means is it *ever* accurate enough that the most sensitive settings are really reliable. And the fact that the display shows an accuracy of 0.1 degrees Fahrenheit is basically meaningless. It's actually far from accurate, to begin with. Yes, and there's no way to tell So not only is the "scanned" temperature not accurate compared to the "reference" temperature, there is no way to correlate it to reality.
