Function Overview: Mainly used for measuring the ring stiffness of plastic pipes with large diameter circular sections. The host adopts high-strength column support and high-precision ball screw transmission, with good rigidity and linear motion characteristics. Choosing load sensors with different ranges can provide accurate measurement data for various range structural styles. Rich fixtures, fixtures, deformation measurement accessories, etc. can almost meet all customer needs. The accompanying FastTest V1.2 software is simple, fast, and convenient, making the user testing process easier. Applied to higher education institutions, new materials, building materials, quality inspection and other fields.
