AST AL390 Operation Manual

Highly Accurate Non-Contact Pyrometer With Analogue Output and Digital Interface
300°C to 1400°C
AL390 IR Pyrometer model provides the advantage of noncontact 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 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.
