Infrared thermometers can be calibrated for accuracy just like other thermometers. It depends on what you plan on doing with the data. In this article we will explain how you can calibrate an infrared thermometer. An adequate uncertainty budget should help point these out. There are two which cause people more problems than others, emissivity, and size-of source. How to calibrate the Infrared thermometer using an ice bath? You could probably get Fluke to do the calibration. An accurately calibrated thermometer is an essential tool for measuring temperature. It’s best to test both ice-point and boiling-point calibration, as thermometer sensitivity may differ at extreme ranges. And you can use a comparator to verify your result. TTFN (ta ta for now) I can do absolutely anything. Firstly, calibration points should be tested based on the range of temperature for which you're calibrating the IR thermometer: If they're over a wide range of temperatures, a minimum of 3 calibration points should be used, while a narrow range requires only 1 or 2 points.

If a calibration point below the dew or frost point is made, a provision should be made to prevent ice or moisture build-up on the calibrator surface. If you are going to calibrate infrared thermometers, make sure that the calibrator you use is calibrated on the same wavelength that you are measuring.

Infrared Thermometer Calibration infrared thermometer calibration standard. For other manufacturers’ models, this information should come from the infrared thermometer manufacturer or be determined by experimentation. An Infrared thermometer, also known as IR thermometer is a thermometer that is a non-contact type, which means it can measure a body’s temperature without making contact. As with any type of calibration, you need a reference point by which you can compare the thermometer. Always calibrate a new thermometer, one that has been dropped on a hard surface, or one with a temperature reading that is off by more than +/- 2°F (+/-0.5°C). Note: If the ice floats up off the very bottom of the glass at all, the ice bath is likely warmer than 32.0°F (0.0°C). To calibrate your infrared thermometer with an ice bath: Step 1: Fill a large glass to the very top with ice (crushed ice is preferred but not required). Some infrared thermometers will need to be calibrated with an aperture. Crushed ice solution is reasonably straightforward to use. If neither an industrial black body or a comparator cup are available, however, you can do a quick calibration using a properly made ice bath. The transfer standard is used to calibrate the thermal radiation source. How to perform verification to determine the accuracy of IR thermometer; What is an Infrared (IR) Thermometer. Before the calibration, the infrared thermometer should be allowed enough time to reach the temperature of the laboratory, typically 15 minutes. For Fluke Calibration infrared thermometers, a source size of 5 inches (125 millimeters) in diameter is enough for all models. Depending on the infrared thermometer being calibrated and the calibration temperature, additional equipment may be required.

How to perform verification to determine the accuracy of IR thermometer; What is an Infrared (IR) Thermometer. Calibrating Your Infrared Thermometer with a Properly Made Ice Bath. Technicians use industrial black bodies, however, you can do a quick calibration using a properly made ice bath. Calibration procedure. This can be done via the use of a dry gas purg… There are a number of factors that can increase uncertainty and cause errors when using infrared thermometers. Step 2: Add very cold water until the water reaches about one half inch (1 centimeter) below the top of the ice. Even if you are not in a stand to calibrate your thermometer, you can use methods to check your instrument’s accuracy. Once the prep work has been completed and data points have been obtained, it's time to test! Some manufacturers actually recommend sending in the thermometer annually, whether it has a problem or not, for regular calibration. To calibrate the infrared thermometer, you can use crushed ice. In general, you need to make a squished ice and water mix that has a sludge uniformity.

For most calibrations, cleaning the infrared thermometer’s lens is not recommended. If you’ve done an accuracy test (using a calibrator or ice bath) and found the infrared thermometer to be inaccurate, you can send it to the manufacturer for professional calibration. This is an especially important consideration when bringing a thermometer in from the outside. 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. I would guess that it's a yearly thing. Geometry Measuring with an IR thermometer is an optical measurement, so just like binoculars and telescopes there is a field of view.

If neither an industrial black body or a comparator cup are available, however, you can do a quick calibration using a properly made ice bath.

The techniques help to know the accuracy of your thermometer and make prior adjustments to it if there is a need to do so.
