Compression Stress Relaxometer
The Wallace Compression Stress Relaxometer (WAC11) allows the operator to easily measure the Compression Stress Relaxation (CSR) characteristics of elastomers and rubber products (e.g. seals, O-rings) as required by the relevant standards.
- Product Name
Compression Stress Relaxometer (C11)
- Overview
The C11 provides the user with accurate, repeatable and reproducible measurements with an easy operator interface and integrated software. The instrument uses a discontinuous method meaning only one instrument for any number of jigs.

The principle of the WAC11 is based on the electrical contact being made between the load cell and the head of the jig. The contact is only broken when the force applied to the Relaxometer marginally exceeds the counterforce exerted by the test sample. The Relaxometer features a ballscrew-driven motorised test frame and load cell designed to apply and measure the required force. At the start of the test cycle the measuring head moves quickly to the jig. At a pre-set position, the measuring head reduces the speed to allow the load cell to more accurately read the force. When the applied force just exceeds the counterforce, the results are displayed graphically and can be saved to a designated folder.
