Temperature Reference Source - U

Temperature Reference U

  • ICI’s Temperature Reference Source U features a 3.94” (70 mm) isothermal target specially designed to measure
    between 5 °C to 50 °C.
  • It is highly accurate making it a perfect temperature reference for calibrating non-contact thermometers and cameras as well as devices for associated applications.
  • Great for non-contact thermometer/camera calibrations, as well as other associated applications.
  • Our instruments include a calibration certificate that is traceable via international agreement to all major national standard bodies, including the NIST.
