Part Code: P390



P390 is specially designed portable IR Pyrometer for non-contact temperature measurement of metallic surfaces and in flame heated furnaces i.e through flames and flue gas. At a wavelength of 3.9um, hot furnaces gases and clean burning gas flames are quite transparent and therefore permit temperature measurement of substances to be measured.
