Baker / D12R, D6R, D3R Digital Winding Tester 

Integrated testing capabilities

The DR series testers integrate a wide range of electrical tests which meet high quality standards. This instrument supports all major electric tests in a single field portable unit including surge, polarization index, DC HiPot, MegOhm and winding resistance. This instrument complies with IEEE recommendations.

​
Continuous innovation
With the DR Series testers, Baker Instrument Company continues to pioneer new breakthroughs that demonstrate our ongoing commitment to quality, reliability, and
competitive advantage. The DR Series is the result of over 40 years of designing and
building winding test instruments. It is the only tester available today that provides
rugged testing capabilities at a multitude of voltages.​

The power of digital testing
The D12R, D6R, and D3R are the latest digital testers offered by Baker Instrument
Company, an SKF Group Company. These instruments are designed to maximize testing capabilities in a lightweight, sturdy format. Additional testing capabilities have been
added to these testers, to make them a more comprehensive tool for
predictive maintenance. As with the other digital testers, the D12R, D6R and D3R have
high precision testing capabilites that allow data collection in the shop or the field. The
results can then be printed immediately or stored for later use.​
