Panametrics-NDT™'s hand held Epoch LT digital ultrasonic flaw detector is 1.5 in. (38 mm) thick and weighs 2.35 lbs. (1 kg). Applications include weld inspection, bond detection, thickness gauging, and general flaw detection.
The detector features automated transducer calibration, measurement features, and an internal numeric data logger that stores up to a combined 500 calibrations and 10,000 thickness measurements with the expanded memory option.
The detector has a high-resolution LCD with full and split screen views, a 60-Hz-minimum display update rate, and an internal rechargeable NiMH battery pack that typically operates six to eight hours. Additional features include display freeze mode that holds waveform soundpath data; peak memory that simultaneously displays live waveform and peak envelope of A-scan; RF display mode; and selectable threshold positive/negative or minimum depth alarm modes.
Several application-specific software options that can be activated remotely are available: distance amplitude correction (DAC); time varied gain (TVG); AWS D1.1 and D1.5; expanded memory; low PRF; echo-to-echo thickness measurement; and extended range.
