Key Features

  • AL Series Digital Infrared Pyrometers with Thermopile Sensors are available in short and long spectral ranges for variety of applications. AL30 model for Non-metallic surfaces, Painted, Coated or Anodized metals, AL390 for through the Flames and Flue gases while AL514 is particularly used for Glass surface temperature measurement.
  • AL45 are special pyrometers which provides the advantage of measurement of flames and combustion gases that include Co2.
  • The pyrometers are equipped with user selectable Analog Outputs 4 – 20mA, 0 – 20mA, 0 -10 V.
  • The pyrometers are provided with Digital USB2.0 output and RS-232/RS-485 for easy communication between the Pyrometer and PCSoftware “Infrasoft”.
  • Laser Pilot Light is provided for high precision targeting.
  • “Software Infrasoft” is under standard scope of supply. Some of the parameters adjustable via software are Emissivity, Response Time, Analog Scale (Sub Range), Peak Picker etc
