With the help of picture-in-picture technology, lots of modern infrared thermometers can easily monitor heat distribution.

With the launch of the new infrared thermometer PCE-TC 24, PCE Instruments is introducing an interesting maintenance tool onto the market that measures temperatures within a range of -20 to 380 °C. The temperatures are displayed as real images with a resolution of 240 x 320 pixels and IR images (infrared images) with a resolution of 33 x 33 pixels. The backlit LCD also allows measurements in dark environments. Non-contact infrared thermometers enable the user, for example, to detect thermal bridges or hot parts, which allows them to discover thermal problems in electrical systems, to locate mechanical failure and thus to arrange the needed maintenance work and save energy. The thermal imager continuously measures the maximum and minimum temperatures of the object to be measured and shows their exact locations. The emissivity (value that defines how easily a material or an object exchanges thermal radiation with its environment) can be set in the menu of the PCE-TC 24, to a value within the range of 0.1 to 1. Additionally, the intergrated memory function allows documentation and archiving. The BMP files can then be read out via microSD card or USB.

An IR thermometer quickly shows results and errors caused by a lack of thermal contact can be ruled out. Another advantage infrared thermometers have over common thermometers is that moving objects can be measured. The light weight of only 295 g, the compact dimensions of 195 x 100 x 55 mm and the included belt bag makes the meter very easy to carry. With its versatile features, the infrared thermometer PCE-TC 24 is a perfect fit for various applications and working areas.
