Platinum Resistance Data Logger
The PT-104 is a four-channel temperature measuring data logger. It offers the ultimate in resolution (0.001 °C) and accuracy (0.015 °C). Along with temperature it can also be used to measure resistance and voltage.
For over twenty years I have used Pt104 temperature loggers in both incarnations (serial RS232 and USB). I have used them for the measurement of temperatures in gas volume calculations. Using them with 4-wire Pt therms, paired and calibrated with the Pt-104’s I have found very problems with these units. Using the provided SDK it has been straightforward to write bespoke software in VB, VB6 and C.
All together and excellent and cost effective solution
