A450C PL/TL is a highly accurate digital two colour IR pyrometer from A series family for non contact temperature measurement. The Pyrometer measures the temperature of an object by calculating the ratio of the energies at two different wavelength bands. The ratio technique eliminates and reduces errors in temperature measurement caused by changes in Emissivity, Surface finish and energy absorbing materials such as Water vapour etc.

Details : The two colour IR Pyrometer is used to measure the temperature in variety of applications in Steel(Induction heating,Forging, Annealing, Welding, Sintering and Rolling mills), Cement(Kiln burning zone ), Glass(Gob temperature measurement) and Crystal growing.

Features :

  • Wide temperature ranges from 600oC to 2500oC.
  • Spectral range 0.7 μm....1.15 μm
  • Fast response time within milliseconds
  • Two Color model
  • Laser targeting / Through the lens view finder sighting options
  • Analog output options available like 0...20mA, 4...20mA and 0...10V
  • USB2.0 Digital output and RS-232/RS-485 Serial interface
  • User friendly PC software for communication
