DAKOTA ULTRASONICS PX Series has arrived. The variety of features offered in the PX-7 and PX-7DL allow the user to select a quality tool that will meet or exceed their specific application needs. In the Echo-to-Echo Mode you have the ability to measure the thickness of materials without removing the paint or the coating. Our 5 year limited warranty indicates how we feel about the reliability and durability of the PX SERIES.

The PX-7DL has all the features of the PX-7 plus  a data logger that stores a total of 1000 readings in 10 files of 100 readings each file.  Our DakView java-based PC or MAC OSX software makes this a complete kit.
