DeFelsko PosiTector IRT
Infrared Thermometer
Non-contact surface temperature measurements


The PosiTector IRT measures the thermal radiation emitted by an object without requiring contact. The PosiTector IRT has a larger distance to spot ratio and button activated laser pointer for precise and accurate surface temperature measurement.



  • Surface temperature is constantly updated and displayed simultaneously
  • Button-activated laser pointer for simple, accurate targetting
  • Enhanced one-handed menu navigation
  • RESET feature instantly restores factory settings


  • Certificate of Calibration showing traceability to NIST included (Long Form)
  • Fast response precision sensor provides accurate, repeatable readings
  • 5:7:1 distance to spot ratio
  • Smart Trend indicators identify rising, falling or stable readings.

  • PosiTector body accepts all PosiTector IRT, DPM, 6000, 200, RTR, SPG, SST, SHD and UTG probes easily converting to each gage.
  • Set a custom emissivity value or adjust to a known temperature.
  • Selectable emissivity values - choose from 7 preset material options: Aluminum = 0.07, Zinc = 0.25, Concrete = 0.54, Paint = 0.96, Plastics = 0.94, Steel = 0.95, Wood = 0.95.
    Depending on surface treatment, metals such as blasted steel can have a broad range of emissivity values. Adjusting to a known temperature (measured by a direct contact surface temperature probe) on a sample will asist in obtaining an accurate emissivity level.
  • High contrast LCD with backlit display
  • Auto rotating display with lock to prevent unintended rotations
  • Uses alkaline or rechargeable batteries (built-in charger)
  • Solvent, acid, oil, water and dust resistant - weatherproof
  • Non-contact sensor won't get caught or worn
  • Shock-absorbing, protective rubber holster with belt clip
  • 2-year warranty on gage body and probe

  • Statistics Scan Mode - continually displays / updates average, standard deviation, min / max surface temperature and number of readings while measuring one reading per second
  • Screen Capture - save screen images for record keeping and review
  • Pause function allows readings to be manually recorded
  • HiLo alarm audibly and visibly alerts when readings exceed user-specified limits
  • Sealed USB Port for fast, simple connection to a PC and to supply continuous power. USB cable included
  • PosiSoft USB Drive - stored readings and graphs can be accessed using Universal PC / Mac web browsers or file explorers. No software required.
  • Every stored measurement is time and date stamped
  • Software Updates via web keep your gage current
  • Software Solutions for viewing, analyzing & reporting data
