1 Introduction
1.1 Main Application
AM1730 Secondary Reference Platinum Resistance Thermometer
(PRT) is an interpolating instrument converting temperature to
resistance. It works together with readout device to measure
temperature or change of temperature. It has wide applications for
dry-wells or temperature baths.
1.2 Main Features
 High accuracy: 0.015 ºC at 0.01 °C
 Temperature range: : -200°C to 420°C
 Durable and shock resistance
1.3 Calibrations
It is recommended to calibrate this PRT annually over the full
temperature range. 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.
