The flexible ultrasonic flaw detector ECHOGRAPH 1094 is a testing electronic for stationary and mobile testing. The device is based on the technique of the well-proven ECHOGRAPH 1090. In addition, the multiplex technique allows to control up to 8 test channels. During testing, all 8 A-scans are being displayed at the same time (overlay mode). The delay time of the transmitters and the adaptation of the amplifiers can be selected individually for each test channel or probe. While working in single-channel mode, the device provides evaluation of the flaws based on the DGS and DAC technique.
