AL390
Temperature Range: 300°C to 1400°C
Highly Accurate Non-Contact Pyrometer With Analogue Output and Digital Interface
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.
