About This Calculator
This calculator determines temperature sensitivity coefficients for Standard Platinum Resistance Thermometers (SPRTs) using the official ITS-90 reference function. Enter your SPRT’s nominal resistance at the water triple point (0.01°C), the temperature of interest, and optionally a resistance change to calculate the corresponding temperature change.
