Work description
National Physical Laboratory requires a new argon triple point realisation apparatus which is capable of achieving the uncertainty required of a top tier National Measurement Institute. The argon triple point occurs at a temperature of -189.3442 °C. It is principally used for calibration of standard platinum resistance thermometers (SPRT) in order to realise and disseminate the International Temperature Scale of 1990.
