A thermometer has two important elements: (1) atemperature sensor(e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical va...
To test for the boiling point, again assuming your thermometer is designed to read in that temperature range, place a pan about three quarters full of water over medium heat and bring it to a rolling boil. Once it is boiling, carefully read the temperature, locating the tip of the probe ...
This video demonstrates two methods for calibrating a digital thermometer: first, with ice and boiling water, and second, with our Fluke dry-block calibrators. Both methods are easy and fast. However, the water method has inaccuracies that are unknown caused by variations in altitude, atmospheric...
Thermometers are instruments that can be used to measure temperature. Learn how to read a thermometer by discovering the scale, increments, and temperature readings of thermometers. What Is a Thermometer? Have you ever been sick with a fever? More than likely, someone in your family used a ...

How to Test Your Windows Computer's Temperature Use a free or low-cost monitoring program to check the internal temperature of your computer's CPU to see if it is running too hot. If your PC showssymptoms of overheating, such as the fan constantly running or the screen frequently freezing,...
This article summarizes what you need to verify that your Fluke 67 MAX Infrared Thermometer is performing within its published specifications. Note that we are only talking about verifying the thermometer, not adjusting it. If your 67 MAX requires adjust
Overheating: Overheating can cause the MOSFET to fail and can be identified by a burnt smell, discoloration, or visible damage, or by measuring the temperature with a thermometer or thermal imaging camera. Gate oxide failure: A gate oxide failure can cause the MOSFET to leak current, leading ...
Ideally, the thermometer will be checked as close as possible to the expected temperature measurement. For example, the expected temperature of the gas in a pipeline. Personal electronic thermometers (PETs) can be verified in the field with a portable dry well. The dry well is set to the exp...
What is the accuracy of infrared thermometer? The accuracy of infrared thermometers is generally ±2°C. In order to obtain accurate temperature readings, the distance between the thermometer and the test target must be within a suitable range. The so-called "spotsize" is the area of the meas...
