We measure accurate temperature in extreme conditions


A4-S-EX is a Multi-wavelength plug and play pyrometer scanner use application specific data base derived from years of experience in real application.A4-S-EX use special algorithms to accurately calculate both the actual temperature and emissivity of the surface.A4-S-EX can hold multiple data base so that single instrument can be easily switched between multiple application like Molten metal, Extruded profiles, Rolled aluminium surface, Continuous casting, Aluminum billets, Slabs etc.
