Just received my Maverick ET-733 today. Question I have is, am I correct to assume that a properly calibrated thermometer should pass both the ice water and water boil test? The posted tolerance from Maverick is +/- (3-4). I tested mine fresh out of the box with the 3' leads that came with it and the Hybrid 6' leads I purchased. Here are my findings. I got the same results for all 4 leads so I know they are all good. I also tested with my ThermoPop Ice water test. Performed by filling a glass with crushed ice and then water to 1/2" below the top. Probe 1 - 41 degrees Probe 2 - 39 degrees Instant read ThermoPop - 32 degrees Water boil test. Probe 1 - 214 degrees Probe 2 - 212 degress Instant read ThermoPop - 212 degrees I did email Maverick and am waiting for a response. I would assume that it should read accurately at high and low temps. I am not necessarily concerned since I don't need a thermometer to tell me when my beer is cold and my Zero Zone has a digital readout for the refrigerator and freezer. Since it passed the water boil test and I mainly will be using it for Brisket and Pork butt do you think I should be happy with it or should I demand they send me a new one?
