Pyrometers Pyrometers are ideal for taking accurate measurements of temperature without contact. Thanks to the optical mechanism utilised by the pyrometers, these pyrometers are safe for measuring high temperatures. Their infrared capabilities make pyrometers the perfect tool to use when conventional sensors are inadequate. This is in cases when the object is moving, extremely hot, in a difficult place to access or due to contamination or other such negative influences. A large variety of handheld pyrometers are listed in the links below. We are available to answer your queries about pyrometers and the best one to suit your needs. They can be calibrated to meet ISO standards, except the PCE-880 and PCE-888 pyrometers. If you can't find the pyrometers you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 (0)2380 987030 and our technical staff will advise you regarding our products.Our engineers and technicians will be happy to help you with the pyrometers, and of course, with the other products in the field of regulation and control, and scales and balances.

Pyrometers with adjustable K value (emissivity) can be used for measuring the temperature of different materials. Here you will find a table with K values for a diverse range of materials (the table can also be seen lower down this page). All pyrometers are shipped calibrated. An optional ISO calibration certificate (laboratory calibration and certificate) can be acquired for all devices, except for the PCE-880 and PCE-888 pyrometers. Below are some images of pyrometers being used. Contact us if you have any questions: our offices on: +44 (0)2380 987030.

Here you can see some images of pyrometers in use: areas of use for pyrometers. The relationship between the diameter of the measurement point and the distance of measurement (ratio) is always shown on the pyrometer in this way, 8:1, 12:1 or 35:1. The diameter of the measurement point increases when the distance from the pyrometer to the object being measured increases. This means that the measurement point can increase at long distances up to a diameter of 25cm. The graphic that can be seen below also shows this relationship. These pyrometers have, at a short distance, a much more moderate measurement point diameter for example at a distance of 30cm the measurement point would be 6mm. Such pyrometers are used for measuring temperature of small areas at short distances.
Example of a surface being measured with a ratio of distance to size of measurement point of 50 : 1
Emissivity depends on the wave length of what is being measured. Please read the user's manual carefully to know the wave length measured by the device you are using. Note: The values shown below depend on the actual state of the material and the measurement conditions.
General information about the principal function of pyrometers: Infrared radiation is an element of solar light that can be seen when light is defracted through a prism. This radiation contains energy. At the beginning of the 20th century, a group of scientists consisting of Planck, Stefan, Boltzmann, Wien and Kirchhoff defined the activity of the elecromagnetic spectrum and they established equations describing infrared energy. This allows the energy to be defined for pyrometers taking into account the emissivity curves for dark objects. Objects with a temperature higher than absolute zero radiate energy. The amount of energy increases in proportion to the fourth magnitude. This concept is the foundation for pyrometers. With emissivity there is also a variable that takes into account average temperature, and this can vary. The emissivity factor is a measurement for the relationship of radiation that a grey object and a black object emit at the same temperature. Pyrometers are produced in many configrations that differ in optics, electronics, technology, size and shape. All pyrometers have one thing in common: the channel for signal processing. It starts with an IR signal, and ends with an electronic output signal.
