1.1 Main Application
AM1860/1850 Standard Platinum Resistance Thermometer (SPRT)
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
 Extreme low drift rate
 Metal sheathed
 Great reference thermometer for dry block calibrator
1.3 Calibrations
It is recommended to calibrate this SPRT 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.
