The black body is an ideal body that absorbs all the electromagnetic energy it receives, whatever the direction of incidence, without reflecting or scattering it.<\/h4>\n

Thus, the thermal radiation spontaneously emitted by ordinary objects or the environment<\/em> (walls, floors, furniture...) can be approximated by blackbody radiation. This blackbody forms the basis for understanding the physical principles of non-contact temperature measurement <\/em>and to calibrate absorption units.<\/p>\n

In theory, the black body is a closed isothermal solid enclosure, empty and impermeable to radiation<\/strong><\/em>. When brought to a certain temperature, the blackbody cavity offers a excellent temperature uniformity<\/em><\/strong>. Only a small hole in the wall (small enough to have a negligible effect on equilibrium) allows blackbody radiation to be measured.<\/p>\n

In practice at Mesurex: a hollow copper sphere<\/em> (\u00d8100, others on request) is coated with high-temperature, matt black multilayer paint<\/em> (up to 600\u00b0C). It features a hole for instrumentation of a measurement probe<\/em> according to customer requirements (thermocouple or PT100, sensor diameter and cable length on request). In addition, it can be fitted with a hanging system<\/em> so that it can be easily hung or installed in a variety of positions. This simple yet highly effective instrument is ideal for measuring\u00a0 -40\u00b0 to +80\u00b0C<\/em>, very stable, with a accuracy of 0.15\u00b0C<\/em> (Pt100 mounting).<\/p>\n

The measurement method applied with this dark radiation probe provides a excellent measurement result representative of the average value of the measured space<\/em>. The black ball is particularly suitable for monitoring the ambient\u00ab temperature\u00bb<\/strong><\/em> in large premises<\/strong><\/em> (open spaces, industrial\/logistics halls, veterinary laboratories, etc.), or to measure radiation from heating systems, machines or sunlight, or for legal or insurance purposes to establish the average radiant temperature of a given environment.<\/p>\n
