Thermographic paints with high emissivity allow accurate non-contact temperature measurement. . Many materials (metal, glass, some plastics) with a glossy surface and high reflectivity, with unknown or low emissivity, cause inaccurate or impossible IR camera measurement. Barvy LabIR® Paints thermographic paints create a homogeneous layer with high emissivity for very precise measurements.
For specially designed paints, we are the only company in the market who guarantee emissivity for a given wavelength, emissivity dependence on the viewing angle and also other characteristics: mechanical resistance, optical impermeability, etc.
The various kinds of paints are adapted to specific environments for low-temperature and high-temperature use.
Thermographic paints offer
Thermographic spray paint for standard applications
Paints with high mechanical resistance suitable for routine measurements up to 100 °C, for uncooled infrared cameras and for applications on electrical equipment. The best value offer.
Thermographic spray paint for high-temperature applications
Durable paint with high emissivity, resistance and stability at high temperatures.
Washable spray paint for thermography applications
Paint with high emissivity is easily washable by water without using chemicals or coarse mechanical methods. Suitable for measurement locations where permanent paint application is unsuitable. Paint is applicable at room temperature.
Why use LabIR® Paint for non-contact temperature measurement?
You can achieve the best results of non-contact temperature measurement only for high emissivity coatings. For low emissivity coatings with high reflectivity, measurement is complicated, not very accurate or even impossible.
Thermographic paints create high emissivity and homogeneous coatings on a hard to measure surface. Properties of thermographic paints defined in detail enable exact temperature measurement of the basic material.
Knowledge of emissivity is the key to quality measurement
We are the only one able to define the exact properties of thermographic paints in a wider context. Most sellers only indicate the value of emissivity without any other context. This number may change significantly based on other conditions.
Our paints are therefore tested for different wavelengths, the emissivity dependence on the viewing angle , the spectral dependence of the transmissivity. We know precise mechanical and thermo-mechanical properties.
For accurate measurement, it is not the determinative emissivity value that is important, but precise knowledge of it!
