Unrivaled quality

The technicians who build our devices understand the company’s commitment to quality. Every unit is checked a second time by a quality control person before shipment. Epsilon is accredited by A2LA to the ISO/IEC 17025 international calibration standard and certified by DNV to the ISO 9001 international quality management system standard. Epsilon uses a laser interferometer for increasing the accuracy of much of what we measure. This allows calibration of extensometer calibrators as well as extensometers. With an accuracy of 0.5 parts per million, it approaches the measurement accuracy of national standards. Our scope of accreditation and quality system certificates can be viewed here.
