Temperature Reference Source I - Mini

Temperature Reference I Mini

  • Small in size, our device measures less than 3” in any direction allowing it to fit into the smallest of spaces.
  • ICI’s Temperature Reference Source I Mini features a 35 mm (1.375”) isothermal target specially designed to measure between 35 °C to 37 °C (95 °F to 98.6 °F.
  • It is highly accurate making it a perfect temperature reference for non-contact calibration and associated applications.
  • Our instruments include a calibration certificate that is traceable via international agreement to all major national standard bodies, including the NIST.
