Simplify data analysis in force, materials and torque testing
Test calculations are the values derived from raw measurement data, such as peak force, torque angle, or modulus of elasticity. With advanced software, these are now calculated instantly and with high precision, replacing error-prone manual methods.

Compression Testing in Top Load Applications
A typical challenge in packaging, and bottling applications is trying to balance product integrity, where the container might be too weak and crush under load, and excessive raw material cost, where the container is too strong.
