Compu-Spring is a revolutionary new computer based valve spring testing system. It consists of a rugged spring test stand that provides highly accurate spring pressure and length measurements. The test stand plugs in via USB to any PC compatible computer, from laptops to desktops. A special software program program then turns your computer into a powerful valve spring test and analysis system. Using the tester requires no computer expertise or special training, since as shown below, all commands are listed right on the screen.

The PT-200 is not only the most accurate valve spring tester available, its also the fastest. You can measure and printout a full V-8 set of valve springs in less than 5 minutes.
