A150 is a specially designed highly accurate digital IR Pyrometer operating at the near end of the infrared spectrum and is therefore an excellent choice for measurement of ferrous and non ferrous metals above 75oC because the emissivity of un-oxidized metalsurfaces is higher at shorter wavelengths. The parameters like Emissivity, Analog output, Sub-range, Response time and Peak picker can be preset ex-works or adjusted via software. This enables the instrument to be adapted for various measuring tasks.

Details :

  • A150 Infrared Pyrometer is provided with USB 2.0 connector with cable.The infrared Pyrometer can be powered through USB port. In this case no external power supply is required (+24V DC is required for operation of Analog output, Laser, RS- 232/RS-485 output.
  • The pyrometer has solid body in stainless steel housing which provides high operation safety even in rough industrial environment. Variety of working Distances with fixed focus available for different applications.

Features :

  • Wide temperature ranges from 75oC to 700oC.
  • Spectral range 2 μm...2.6 μm
  • Laser targeting
  • Fast response time within milliseconds
  • Analog output options available like 0...20mA,4...20mA,0...10V
  • Digital USB2.0 output and RS-232/RS-485 Serial interface
  • User friendly PC software for communication

Standard Scope of Supply :

  • Pyrometer with Laser pilot light(PL)
  • Analog output 4...20mA,0..20mA, 0..10V
  • Digital USB 2.0 output with USB Cable
  • Digital Interface RS-232 & RS-485(user selectable),
  • 5 mtr long connection cable with connector,
  • 1.5 mtr. Communication Cable,
  • Calibration certificate, Software & Operation manual.

Optional :

  • Mechanical and Electrical Accessories
  • Extra Cable Lengths

Applications :
