NOPIX NON-CONTACT VIDEO EXTENSOMETER – BMT-EV
High-Precision Extensometer for Material Testing.
Designed to eliminate the limitations of contact-based extensometers, our Non-Contact Optical Extensometer,Nopix, performs deformation measurements across a wide range of material testing applications fully optically and without contacting the sample. As a high-performance video extensometer, it succeeds where contact-based extensometers fail and with its higher accuracy it can be the modern alternative in all applications where traditional extensometers are used. Nopix is the right video extensometer choice if the application requires no load added to the specimen,tracking multiple gauge points/regions simultaneously and capturing full-field deformation while maintaining high accuracy as well as reliability of the results.

Frequently Asked Questions
What is a video extensometer?
A non-contact optical device that measures strain and deformation of a specimen during material testing, using a camera and image analysis instead of physical knife edges.
How does Nopix measure strain?
It uses Digital Image Correlation (DIC). The camera tracks surface points on the specimen in real time and LitRay calculates displacement and strain from them.
Which tests can Nopix perform?
Tensile, compression, flexure and torsion tests on metals, plastics, composites, construction materials and more.
Which standards does Nopix comply with?
ISO 9513 (Class 0.5) and ASTM E83 (Class B1a).
Can Nopix replace a clip-on extensometer?
In most applications, yes. It adds no load to the specimen, is not damaged at break, and can track several gauge lengths at once.
Can Nopix be used with my existing testing machine?
Yes. It works with BESMAK machines and with major third-party controllers, including Doli, through analog and serial outputs
