So I decided to give my ET73 and my Weber Style a check this morning. I filled a glass with ice and enough water to fill the spaces. I started a pot of boiling. Since the Weber is a food only thermometer I did only the ice water test. The Weber in the ice water read dead on 32 degrees most of the time and then bounced to 33 and held. The Weber seemed very sensitive to movement of the sensor. A slight bump would increase the temp but it would then settle back down. The Maverick in the ice water hit 34 degrees and wouldn't budge. The Maverick in the boiling water would hit 211. At times the transmitter would bump to 212 but the receiver didn't catch up to it and it stayed at 211. I am happy with the boiling water test of the Maverick. My question is do I now subtract 2 degrees from my Maverick meat probe reading everytime I am cooking something? Oh I forgot to add I let the probe of the Maverick just dangle in the boiling water never touching the sides of the pot. If I just dropped the probe into the boiling water and let it submerge it would read 212 to 213.
