Product Description
The WRT-II uses electronic and digital control technology to measure how the resistance of conductive materials changes with temperature. Plotting the resistance–temperature curve supports qualitative analysis of the resistance change rate. The instrument is intended for research and teaching demonstrations in college and university electronics-material laboratories.
A USB interface connects the tester to a computer for automated test analysis. The supplied software environment is legacy Windows 10/7/XP.
