Electric Open Water Propeller Dynamometers

Product Description

Electric Open Water Propeller Dynamometers

The three dynamometers are of the same general type but differ in size and capacity as shown below. The dynamometers can be supplied with the standard height of the vertical streamlined profile or with an increased height of the vertical streamlined profile as described below.Full technical details of the dynamometers are provided below.
