At a wavelength of 3.9um hot furnaces gases and clean burning gas flames are quite transparent and therefore permit temperatures of substances to be measured as well during heating up process in industrial furnaces with the use of infrared Pyrometer AL390.

This format combines the high accuracy of digital signal processing with the simple connection AL390 IR Pyrometer is used for target temperature ranging from 300°C to 1400°C. The electronic assembly is protected by IP65 rugged stainless steel housing. AL390 IR Pyrometer is provided with USB 2.0 for parameter setting & Data Logging.
