The new, patented, single rotor tube prony brake design, brings both the DT843 and DT526 dynamometers into the 21st Century. This new design was built from the ground up. It’s a product of thousands of hours of development, design, and testing. This, along with more than 100+ years of manufacturing, field service, design, and application experience, back up this new prony brake concept.
