How To Calibrate Food Thermometers (Digital & Analog)

To cook meat and poultry to perfection, you need an accurate food thermometer. But after years of use, that one time-reliable digital or analog thermometer might need to exist calibrated. Two or three degrees off makes all the difference betwixt a medium-rare roast and a well-done roast as you lot tin can see from our meat temperature guide. If yous don't ain a meat thermometer, check out our review of the best ones.

Make sure your thermometer has a reset button

Calibrating a digital meat thermometer is a very easy, two-step process. However, you practice need to first see if your thermometer has a scale reset push button, like 4 of the seven thermometers we tested. If it doesn't have a reset or other way for calibration (read your thermometer's instructions, if you lot withal have them), you tin still cheque the thermometer's accuracy by performing these two tests.

One of our top picks for accuracy and reliability, the EatSmart has a calibrate button that helps yous make sure the thermometer hits the correct temperature every fourth dimension.

Ice water test

Make full a tall glass with crushed water ice and add together cold water. Stir the ice and water for iii minutes. Insert the thermometer'due south probe two inches into the center of glass — endeavour to keep the probe from touching water ice — and hold information technology there for xxx seconds. (An instant-read thermometer volition register a temperature in most 10 seconds; a wired probe will take longer.) Your thermometer should read 32 ℉ or 0 ℃. If information technology doesn't, push the reset or calibrate button (commonly designated on the thermometer as CAL), until it hits 32 ℉ or 0 ℃.

Boiling water exam

Bring a saucepan of water to a rolling boil. Insert the thermometer probe into the center of the pot, almost two inches into the water. Concord it for xxx seconds (employ a pot holder or dish towel to protect your fingers from the hot steam). Your thermometer should register 212 ℉ or 100 ℃. (The boiling signal for water is lower in high-distance locations.) If it doesn't, button the reset or calibrate button until it does.

Afterward conducting these ii tests, yous should have a perfectly calibrated meat thermometer. If your thermometer isn't authentic and tin't be calibrated, so consider purchasing a new one, particularly since they're so reasonably priced.

How to calibrate an analog thermometer

An analog thermometer can exist calibrated using the same methods. Information technology's piece of cake plenty to check the thermometer'south accuracy with the ice water examination.

Plunge the tip up to two inches into the eye of the iced water and wait several minutes to see how close information technology measures to 32 ℉ or 0 ℃.
If the reading is off, remove the thermometer from the water and turn it upside down. You lot'll see a 6-sided nut under the dial — this is the calibration nut — and it tin can be adapted using a wrench.
Make a slight adjustment to the nut, and so put the tip into iced water again. It should now be calibrated to 32 ℉ or 0 ℃. If not, so adust the scale nut once more.

You can also calibrate the thermometer to 212 ℉ or 100 ℃ past using the boiling h2o exam. Merely when you lot lift the thermometer out of the boiling water and adjust the scale nut, apply protective manus covering. Alternatively, you can wait until the thermometer has cooled, adjust the calibration nut, and retest the thermometer in the boiling water.
