Engine and Chassis Dynamometers, Transmission
Test Stands, & Data Acquisition Systems and Controls
Producing some of the world's finest dynamometers and equipment since 1976.



For years, customers have relied on the Maxwell dynamometer. In 2005, Power Test purchased the assets of Maxwell Dynamometers. We are able to provide current owners of Maxwell heavy duty chassis and engine dynamometers with the latest in data acquisition and control systems.
For current Maxwell emission systems owners, we suggest that you contact your service provider as outlined in your original purchase contract.
