Icarus – ITS-90 Software for SPRTs

Icarus is designed to calculate and display the relationship between resistance and temperature for Standard Platinum Resistance Thermometers between the triple point of Hydrogen and the freezing point of Silver. All calculations are performed using the equations and values defined in the International Temperature Scale of 1990 (ITS-90).

  • Calculate ITS-90 Coefficients
  • Generate coefficients from data or data from coefficients
  • Design and Print Certificates
  • Use powerful keywords and conditional statements
  • Check the calibration quality
  • Fit extra calibration points to the curve
  • Icarus is used at Isotech in our accredited laboratories to create certificates for PRTs and SPRTS calibrated in ITS-90 Fixed Point Cells.
