[1] "Accuracy" is a difficult term when used to describe a resistance thermometer. The simplest way to derive basic "accuracy" is to combine the probe drift specification and calibration uncertainty with readout accuracy at a given temperature.

[2] Three thermal cycles from min to max temp, includes hysteresis, 99.9 % confidence

[3] After 100 hours at max temp, 99.9 % confidence

[4] Per ASTM E 644
