Product Introduction
----------------------------------------------------------------------
EPOCH LTCDigital ultrasonic flaw detector
The EPOCH LTC digital ultrasonic flaw detector embodies the most advanced technology today. The instrument is small in size and lightweight, weighing only 0.96 kilograms (2.12 pounds). The design of EPOCH LTC is based on the technologically advanced EPOCH XT, which is fully functional and complies with the EN12668-1 standard. It not only has a large number of standard performance, but also comes with multiple specialized options to meet the detection needs of users.
The instrument is equipped with a bright color through reflection display screen with full VGA resolution (640 x 480), capable of displaying A-scans at high resolution and displaying images clearly under any lighting conditions, including direct sunlight. The design of EPOCH LTC meets the requirements of IP67, ensuring that the instrument operates normally in the harsh environments commonly found in non-destructive testing sites.
