Profile: Epsilon Technology Corp. is a provider of extensometers. We specialize in materials testing equipment and sensor design. Our 3590VHR uses an integrated sensor, and it has two separate lead screws, a course adjustment for quick travel over large distances, and a fine adjustment that allows the user to easily dial in the necessary target value. The provided software allows the ability to tare the output, and the digital display simplifies calibration of extensometers. Our laser interferometer system allows calibrating the full 3590VHR calibrator systems traceable to NPL. We provide general purpose extensometers for axial tensile, compression, and cyclic testing. Axial extensometer is designed for long gauge length applications where low level strain measurements are required. Our model 3800 high elongation extensometer is designed for plastics, rubbers, and elastomer testing.
