MM

Description

The new Marathon MM Series platform, which covers a temperature range of minus 40 to 3000°C (minus 40 to 5432°F), consists of six IR temperature sensor models, each with a specific measurement wavelength and temperature range appropriate for either low- (minus 40 to 800°C / minus 40 to 1472°F), medium- (250 to 1100°C / 482 to 2012°F), or high-temperature (300 to 3000°C / 572 to 3273°F) production monitoring.

  • High resolution, optics up to 300:1
  • Precision focusable optics
  • Optical and laser or sighting standard
  • Available color video sighting
  • Real time ambient background temperature compensation
  • Easy to use operator interface
  • Rugged stainless steel housing
  • Simultaneous analog and digital outputs
  • Field Calibration Software
  • Windows® DataTemp Multidrop software for data acquisition, display and analysis
