For those far above sea level, this correction is worth doing, if calibrating a thermometer using boiling water. | |

Aug 9, 2017 at 6:23 | comment | added | Harry Svensson | Don't forget about the pressure, that's probably 25°C... at 1 bar. Are you sure that the pressure is 1 bar? Also, the thermistor's come with errors, they are usually within a 5% margin. Maybe 20% if you bought it from china. But it looks like a simple calibration problem. Get a regular thermometer (analog or digital), put it in the fridge together with the NTC until you get the temperatures you want and then measure the resistance at those times. | |
