QSV DL

With the QSV DL the test piece thickness needed to measure sound velocity must be manually entered to the unit.

All QSV models feature 1 point Auto calibration, a graphic LCD display with large digits, a coupling indicator and on the QSV DL readings stored in the unit memory (up to 5000) can be transferred to a PC using DMQ DataCenter software.
