Additional Information

The Thomas Traceable Big-Digit Thermometer measures temperature in freezers, refrigerators, offices, and storage rooms. The thermometer measures temperature from -50 to 70 degrees C (-58 to 158 degrees F), with an accuracy of + or - 1 degree C. The 0.8" temperature sensor is attached to the base by a 10-foot cable and can be submerged. The LCD display has 1-1/8"-high digits and shows both probe temperature and ambient temperature. The minimum/maximum memory feature allows high and low temperatures to be recorded for extended monitoring periods. The thermometer is traceable to National Institute of Standards and Technology standards, indicating that it is calibrated to International Organization for Standardization (ISO) 17025 levels. This Thomas thermometer is used to measure temperature in food service, scientific laboratories, and industrial settings.

Digital thermometers are instruments used to measure the temperature of air, liquids, or surfaces electronically. They may measure temperature in Celsius, Fahrenheit, or both. Most digital thermometers use thermistors, which are small electronic resistors. Thermistors are made out of metals that conduct electricity within a certain range and become more conductive the warmer they get. A microcontroller inside the thermometer measures this electrical conductivity and converts it to a temperature, which is displayed on an LCD. Digital thermometers are used in a wide range of applications, including in laboratory settings, food service and storage, and in doctors' offices and hospitals.

Most Helpful Customer Reviews

I was looking for an accurate outdoor thermometer. Checked against carefully stirred ice water this registered 31.5 F, Quite reasonable. I just wish there was a wireless one which was as accurate.
Perfect for both our comercial refrigerator and freezer. Much more accurate than the one on the front of them. Seems to keep accurate temperature. Have had them about 6 weeks.
This is a pretty cool device!. The first one we got had a pretty extreme difference between the "ambient" and the "probe" temps - with the probe right next to the display unit.. FOUR degrees even though this thing was supposed to be certified. So we returned it (thanks Amazon) and got another one. This one shows about 0.3 or 0.4 degrees difference between the ambient and the probe. Maybe it's a happy accident but it does inspire confidence that this thing reads accurately.

At another level - this thing is handy beyond belief!! When we didn't have it (between the times we sent the bad one back and got the good one), it's amazing how much you miss this guy!! OK, it's only the outdoor temperature, but it sure is nice to know what it is. (We just hung the probe outside through the window and it seemed to work OK even with the window slammed down on the wire.)

So, beyond the utility value, which is not insignificant, this thing is just plain fun!
