The Helixa precision torque tester from Mecmesin has been designed for precise alignment when using the most sensitive torque sensors. It is a significant development in the torque testing of finely engineered electronics components. The Helixa is ideal where rotation of components is very precise, or very light, measuring a range of critical torque features in design and quality assurance. These include breakaway torque in rotary control components, the precise operation of click-stop switches, or the 360º smoothness of mass-produced trimmers and presets. The Helixa is available as a PC-controlled version or as a stand-alone version.
