## Fenwal 10k thermistors, curve 16

Also: (Here's a .pdf with 0.1 degree steps and Fahrenheit conversion. Here's a spreadsheet to make building a lookup table a bit easier.) These values were calculated by me using the Steinhart-Hart equation over several smaller temperature ranges on the theory that would yield a better result. But it's been decades since I did it, so I hope it's accurate and I can't defend it, either! These values do compare well against published values. The values in between integer degrees are calculated by linear interpolation. Grab a 0.1 degree "interchangeable" thermistor and you have a pretty spectacular temperature reference for the experimenter's lab. The chart goes to 100C but I'd recommend not heating such a good thermistor above 70C to prevent temperature-induced drift.
