Automatic Constant Rate of Strain System (ACONS Pro CRS)

The VJ Tech Automatic Constant Rate of Strain System (ACONS Pro CRS) is tailored for Commercial and Research applications, allowing the user to perform a CRS System test in a fully automated manner.

Featuring the latest technology, our CRS System offers seamless automation with closed-loop control. The strain rate can be automatically adjusted by monitoring Pore Water Pressure ensuring adherence to testing standards.

Furthermore, our Automatic Constant Rate of Strain System provides versatile customisation options to accommodate even the most challenging soft or slurry materials, alongside higher precision displacement sensors.
