Features

The WGA-910A is an instrumentation conditioner that employs a touchscreen.
It is capable of monitoring pressure changes in press machine and press-fitting process by indicating the wave forms, and visually verifying changes in physical quantities such as the load, pressure and so on which are difficult to capture with just numerical figures.
