Not a new thread by any means, but I would like to use one to do a quick check of my tanks of milk. I haul from dairy farms to plant. One part of my job is to check tank temps before i accept the milk on my truck. I have a probe type of thermometer that is all calibrated, but i want to use a IR for a quick scan. Temps will range from 32f to 45f on normal ttemps. I don't usually load anything above 42f. Don't want to spend much $$$'s, as it can be a rough use. Not uncommon to drop things, wet environment, etc. Thinking about having it on a string around my neck, not a good thing to drop stuff in the tanks. we won't go there...
