MR1S Infrared Ratio Thermometer

Brand: Raytek

Marathon Ratio Thermometers MR1S use two-color measurement to provide superior accuracy in demanding applications. 

The MR1S thermometers features an advanced electro-optical design, digital electronics and built-in user interface all combined in a rugged, compact housing. 

MR1S thermometers are ideal in situations where the target may be obstructed due to atmospheric smoke or other particulates, where the target is moving, or where the target is smaller than the field-of-view.
Features
  • Provides accurate measurement of targets that are: partially occluded, obstructed by smoke, steam, or particulates, moving, smaller than the instrument field of view
  • Measures from 600° to 3,000° C (932° to 4,532° F) with three models
  • Fast response time down to 10 ms
  • One-color or two-color operation
  • Simultaneous Analog and digital outputs
  • Programmable relay output (dualtemperature setpoints or “fail-safe”)
  • Unique “dirty window” alarm (attenuation measurement US Patent No. 5,815,410)
  • Bi-directional RS485 communications
  • Supports up to 32 Marathon Series sensors on a multipoint network
  • Windows® DataTemp® Multidrop Software (operates under WIN 3.1/95/98/NT4 Windows 2,000, XP)
  • Field Calibration Software
