IST  Spring Test Machines

The tables below show details of our standard load (compression and extension springs) and torque (torsion springs) test machines. Note that we can provide machines in other capacities if required; please contact us for details.

We also calibrate and service test machines, and offer a refurb/refit service to bring your old machine up to date with our control and measurement systems.
