WINRES-20B BLUE – 20 A winding resistance tester
With the WINRES-20 Series winding resistance testers you get a powerful and reliable solution for transformer testing, as well as shunts and other electrical components.
The WINRES-20B BLUE adds extra flexibility with its built-in battery and Bluetooth connectivity, making it the ideal choice for portable test equipment – efficient, accurate, and ready for use in the field or in industrial environments.
The WINRES-20 Series is a powerful and portable solution for winding resistance testing up to 20 A DC.
With advanced functions such as dual measurement channels, automatic stabilization, demagnetization, and heat-run / temperature rise testing, you get reliable results in minimal time.
Thanks to the built-in printer, optional battery, and Bluetooth connectivity, you can work flexibly – both in the workshop and out in the field.
Main benefits
- Test current up to 20 A DC – fast and accurate, even on large windings.
- Two measurement channels – measure two windings simultaneously (e.g. primary and secondary).
- Wide measuring range – from 0.1 µΩ to 100,000 Ω.
- Automatic stabilization – the device itself determines when the measurement is stable.
Demagnetization – removes residual magnetism after each test. - Heat-Run / temperature rise test – simulate operating conditions and check for thermal rise.
- Immediate reporting – via the 7” color touchscreen and integrated thermal printer.
- Mobile and wireless – with Li-Ion battery option and Bluetooth connectivity.
