ALL OUR DEVICES ARE POWERED BY OUR VERSATILE DIGITAL IMAGE CORRELATION SOFTWARE

The Alpha DIC software is an industry-recognized instrument for optical measurement and analysis of deformation, vibration, and strain of virtually any material or structure.

ONE Series Optical Extensometer

ONE series optical extensometers demonstrate state-of-the-art digital correlation technology. All ONE measuring systems deliver accurate and precise strain measurement readings.

Ease-of-use and numerous industry-leading software features make ONE an excellent choice for many applications, including tensile, compressive, bending, shear, torsional and fatigue testing. All this on a wide range of test frames, from the small-scale single-column machines to the largest, four-column UTMs.

Any set of two standard ONE optical extensometers can be converted into a 3D system using the dual mode and the 3D DIC software module.

DETAILED SPECIFICATION

HT Optical Extensometer

HT is a professional optical extensometer for high-temperature applications suitable for temperatures ranging from ambient temperature up to 1400 °C.

The HT uses the same user-friendly DIC software interface as the ONE series, which allows you to focus on the experiment and data acquisition. Besides materials testing at elevated temperatures, the HT is suitable for any application requiring a precise and accurate optical extensometer with a small field of view.

HT TECHNICAL DATA

Field of View: 47 × 41 mm
Resolution ISO 9513: Class 0.5
ASTME 83: Class A (GL > 15 mm)
Gauge Length: Selectable single or multiple gauge lengths
Sampling Rate: 75 – 200 Hz
Axial and radial neck detection
Lighting: Auto-switching monochromatic light

ROD Optical Extensometer

The ROD is an optical extensometer optimized for tensile testing of reinforcing steel. Because ROD is designed for harsh industrial environments, it is equipped with dust-proof casing and glass-protected dual cameras.

The unique ITT functionality of the Alpha software allows for measuring specimens with an oxide or rust layer falling off during testing. This feature gives ROD a significant advantage compared with standard optical extensometers, which are, under such conditions, almost unusable.
