MUX_4md.jpg (24617 bytes)

The QMI 2000 PC  is an ultrasonic PCI card designed to be assembled in multichannel instruments with advanced features for automated nondestructive material testing.

Features:

Each channel consists of an autonomous electronic module (encapsulated PCI card) and containes all the components and features of a complete ultrasonic instrument, such as:

Multichannel operation and display by the QMI 2000 SW application software:
