AM1960/1950 Standard Platinum Resistance Thermometer User's Guide

1 Introduction

1.1 Main Application

AM1960/1950 Standard Platinum Resistance Thermometer (SPRT)
are interpolating instrument converting temperature to resistance. It
works together with readout device to measure temperature or change
of temperature. They are used as primary standards or reference
standards by temperature calibration labs at various levels.

1.2 Main Features

 Extreme low drift rate
 Quartz sheathed
 Great primary or secondary reference standards

1.3 Calibrations

As a temperature standard, each AM1960/AM1950 SPRT must be
calibrated. It is highly recommended that the calibration is traceable to
a recognized national standards laboratory.
Manufacturer recommends calibration interval to be one year. In
between annual calibrations, user should check the drift rate
periodically by comparing the Rtpw value against the last calibration
results. Refer to specifications section for normal drift rate.
