This calculator calculates R_{25} and B for the thermistor model \( T=\frac1{\frac1{T_0}+\frac1{B} ln \frac{R}{R_0}}\) where T and To are absolute (K).
Use this calculator to determine R_{25} and B from T,R pairs measured from either a thermistor or thermometer.
The model is an approximate one, and you will likely get different parameters for different measurement points... though hopefully only a small change. The best thing to do is to use data points towards each end of the intended operating range. It also helps if the first data point is close to 25°.
