Versatile optical extensometer

The Vector U70 is engineered to excel in challenging environments, offering reliable performance in varying conditions such as extreme temperatures and fluctuating lighting. Its advanced non-contact technology ensures precise measurements even in the most demanding settings, including the ability to see through compression platens. This capability makes it highly versatile for applications where traditional methods might struggle.

Optical extensometer mounted to universal test machine

Truly non-contact measurement

The extensometers can be used on specimens up to the point of failure without sustaining damage, making the Vector U70 an ideal solution for critical testing across industries where durability and accuracy are paramount, this ensures more reliable and repeatable results, free from operator influence. Vector’s lightweight operation and convenient integration makes Vector an advancement to any material testing laboratory.

Optical extensometer with easy mounting setup

Affordable solution

The Vector Extensometer range offers a highly affordable solution for materials testing. Each optical extensometer comes with mounting hardware, marking solutions and software included, providing excellent value. Compared to advanced systems like video and automated extensometers, Vector requires significantly less capital investment while maintaining a similar lifetime cost to a single clip-on extensometer system.

Expanding measurement capability

Having adopted and been impressed with the Vector U200 when it first launched, we were keen to explore the possibilities U70 offered with smaller gauge length, sub-sized or compression specimens, it did not disappoint.
