Quick Answer: How To Calibrate Infrared Temperature Sensor?

Short of using a black body, the next best way to calibrate your infrared thermometer is to use a simple, inexpensive Infrared Comparator Cup. It is best to calibrate your infrared thermometer at more than one temperature (at 41°F [5°C] and 140°F [60°C] for example) and the Infrared Comparator Cup makes it easy.

Do Infrared Thermometers have to be calibrated?

Infrared thermometers cannot typically be calibrated at home, but they are known for their low drift. If the results of your ice bath test are within your unit’s manufacturer’s listed specification, you are good to go.

How do I know if my infrared thermometer is accurate?

To test the accuracy of an infrared thermometer requires access to a stable surface of known temperature. You cannot verify the accuracy of an IR thermometer by comparing it to an immersion type thermometer that is beneath the surface of a liquid or semi-solid in a non-controlled experiment.

How do you calibrate a non-contact infrared thermometer?

This can be achieved in a few different ways. However, the simplest way to help calibrate a non-contact thermometer is to create an ice bath for the thermometer to measure. Luckily, this can be done by using a large glass rather than having to fill up an entire bathtub.

Why is my forehead thermometer giving different readings?

The lens of the thermometer is sensitive and reacts not only to changes in temperature but also to dirt or grease. It clogs up the lens and gives you incorrect results.

What is a normal forehead temperature with an infrared thermometer?

It would be normal to read an actual forehead skin surface temperature between 91F and 94F if using a general-purpose infrared thermometer. Some infrared thermometers have an “adjustable emissivity feature”. Some are factory set for emissivity of 0.95, or in the case of our IRFS, 0.97.

How accurate is a forehead temperature reading?

But the temperature readings vary depending on which one you use, and you need an accurate body temperature to determine if a fever is present. A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

What is the simplest in lab method to calibrate an infrared thermometer?

An ice bath is one of the oldest and simplest zero-point temperature source reference standards used in temperature calibration.

How do you reset an infrared thermometer?

To reset the unit, remove the batteries, wait 2 minutes and then re-install the batteries.

What is a normal forehead temperature?

The average body temperature is 98.6 F (37 C). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more.

Can you calibrate a thermometer?

To calibrate a thermometer, you must first test its accuracy in a substance with a known temperature. Then you’ll adjust the thermometer to match that temperature. There are two common methods for thermometer calibration in food service: the boiling point method and the freezing point method.

How the IR Spectrometer is calibrated?

Infrared (IR) spectrophotometers use polystyrene as a calibration standard. A scan of the instrument with a piece of polystyrene in the sample holder will verify the presence of peaks seen on the IR spectra and the relative intensity of the peaks.
