Review on 🌡️ Premium Precision: Thermco ACC310SUP Laboratory Thermometer for Uncompromising Accuracy by Rashan Jimenez

I have the 5 inch version which I think is more accurate than the other two hence the price is higher. The listing appears to be incorrect or at least misleading, so beware the buyer. Mine was NIST certified and I tested it for accuracy using the freezing point of water and the boiling point of water. By placing the probe's tip in ice water next to ice, I obtained 32.0 degrees Fahrenheit and immersed it in boiling water. the water temperature showed 203.5-204.0 degrees Fahrenheit. I live at 5,000 feet and the boiling point of the water here is calculated at 202 degrees. This is accurate enough for my purposes. It takes about 10 seconds for the reading to stabilize when measuring the temperature of ice water. It may take longer when measuring air temperature because heat transfers through water much faster. I'm still on the first set of batteries after about 3 weeks of use, it's about every other day for 10 readings those days. The functionality is simple, on/off and F/Celcius. I haven't tested the auto shut off feature.
