LabIR® Paint
Thermographic paint for high temperature
HERP-HT-MWIR-BK-11
Special thermographic spray paint with high emissivity and high mechanical resistance for long-term applications to high temperature up to 1 000 °C. Precisely defined physical properties and emissivity dependence on the wavelength, viewing angle of an infrared camera and temperature of the measured surface allow accurate results of the non-contact temperature measurement.
