1 Introduction

AM1760/1762 Secondary Standard Platinum Resistance Thermometer

(SPRT) interpolates temperature in the range from -200 °C to 670 °C

on the International Temperature Scale of 1990 (ITS-90). It works

together with a readout device to measure temperature or change of

temperature. It is designed as a secondary standard thermometer to

calibrate other thermometers and to measure temperature precisely in

metrology labs.

 High accuracy: ±0.006 ºC at 0.01 °C

 Temperature range:

 Rtpw Drift < 4 mK after 100 hours at 661 °C

As a temperature reference standard, each SPRT must be calibrated.

Manufacturer recommends calibration interval to be one year. In

between annual calibrations, user can check the drift rate by

comparing Rtpw against the last calibration results. Refer to

specifications section for normal drift rate.
