With all the meals you plan to cook and steaks you want to grill, it’s important to learn how to calibrate a thermometer so you get the perfect meal every time. The best thermometers rarely need to be calibrated, but there may be times where you need to test and adjust your thermometer so it’s kitchen and backyard barbecue ready. Here’s how:

1. Was versteht man unter der Kalibrierung eines Thermometers?

Genau wie Uhren vor- oder nachgehen können, unterliegen auch Lebensmittelthermometer mit der Zeit und dem Gebrauch Ungenauigkeiten. Extreme Temperaturschwankungen, Beschädigungen oder allgemeine Abnutzung können die Genauigkeit eines Thermometers beeinträchtigen. Wenn Sie Ihr Thermometer häufig verwenden, empfiehlt es sich, es monatlich zu überprüfen, um sicherzustellen, dass es optimal funktioniert. Glücklicherweise lässt sich die Genauigkeit Ihres Thermometers testen und in den meisten Fällen kalibrieren, um wieder genaue Messwerte zu erhalten.

2. How Do You Calibrate the Thermometer?

Many thermometers have a nut under their temperature dial that allows them to be adjusted, while most digital models have a reset button. You’ll want to check the package instructions of your device for exact instructions for calibrating your thermometer. There are two methods for testing the accuracy of your thermometer and calibrating accordingly: The Ice Bath Calibration Test and the Boiling Point Calibration Test. Click Hier to find out how you can calibrate your thermometer in an Ice Bath or keep reading to discover how to calibrate your thermometer at Boiling Point.

3. Boiling Point Calibration

If you have the choice between calibrating with an ice bath or boiling water, we suggest you choose an ice bath, that’s because boiling point calibration tests are tricker than ice bath tests. Water boils at 212°F at sea level, but only at sea level, this means that the boiling point varies depending on where you live. This is because atmospheric pressure at elevations above or below sea level alter the temperature at which water boils.For example, water typically boils at 202°F in Denver, CO.

Fortunately, finding the boiling point where you live is easy. First you need to find out your current barometric pressure and elevation where you are, then, simply use an online boiling point calculator to find out at what temperature water boils. Once you’ve got that information, you’re ready to begin your boiling point calibration test.

Schritt 1:

Fill a pot or saucepan at least four inches deep with clean water.

(Note: impurities or salt can significantly affect the boiling temperature of water.)

Schritt 2:

Place the pot on the stove and turn the burner on high. (Do NOT use the microwave.)

Schritt 3:

Wait until the water comes to a strong, rolling boil that does not stop with stirring.

Schritt 4:

As soon as the water reaches boiling, put the tip of the thermometer probe a few inches into the water until the water temperature stabilizes. Be sure to keep the probe in the center of the pot and away from the bottom or sides of the pot.

Check the temperature reading display and compare it to the boiling point in your area. If they are the same, then your thermometer is reading temperatures correctly. If you need to adjust the thermometer, follow the guidelines mentioned by the manufacturer’s instruction manual. However, before you adjust a digital, instant-read thermometer, check that the readings are within the manufacture’s accuracy specifications. (Look for the ±°F on the documentation that came with your thermometer.)  If it’s within the specified tolerance, don’t adjust.

Kann man ein Fleischthermometer auch für Wasser verwenden? 

Fleischthermometer eignen sich zur Temperaturmessung von Flüssigkeiten innerhalb ihres Messbereichs – von Wasser bis hin zu heißem Speiseöl. Um herauszufinden, was Sie messen können, sollten Sie die technischen Daten und insbesondere den Messbereich Ihres Fleischthermometers überprüfen. Das ChefsTemp Final Touch X10 deckt einen Temperaturbereich von -30 °C bis 300 °C ab und kann die Temperatur von Lebensmitteln aller Art messen, von kochendem Wasser bis hin zu Frittieröl.
