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.
