PRTCalc - free PRT / RTD Calculator (EN 60751)
1.03 Download


PRTCalc is a free utility for those involved with PT100 platinum resistance thermometers.
It allows for the accurate conversion of resistance to temperature or temperature to resistance.
PRTCalc conforms with IEC 751 Amendment 2: December 1995.
PRTCalc also knows the values for the earlier issue of IEC 751.

The user may enter custom coefficients to suit individual probes. Probe specific calculations can then be performed
with all entered data available stored alongside a tag name for the platinum resistance thermometer supplied.

RBC Software
2.41 March 2018
(Improved DLL for F900)


The latest version of the code supports both the current automatic and manual models.
The newer automatic model of the RBC offers improved performance, can be immersed into an oil bath
for temperature control, and of course offers vastly reduced operator time.
There is more information on our website here

The latest version of the RBC software is version 2.4, all the DLLs are updated to version 2.4.
This can be considered a new starting point. Earlier versions of the DLLs won’t work with version 2.4 of the RBC software
and version 2.4 of any of the DLLs won’t work with earlier versions of the RBC software.
Anyone who has written their own DLLs and wants to use version 2.4 of the RBC software (or later) will
need to change their function calls to CDECL and recompile them. Otherwise, a fresh installation is all that is needed.
