The EW-990 is a new range of hardness testers to enhance the current range of CV Instruments hardness testing machines. The EW-990 is a video based universal hardness tester offering Rockwell, Vickers and Brinell (250Kg) with the added accuracy of a closed-loop system.
The EW-990 features a combination of advanced optics with a high quality video imaging and a MS Windows driven industrial computer. A 12” touch screen gives a good overview of settings and test results and eliminates parallax when measuring the image.
