Helixa

Precision measurement of caps and closures

Top-loading capability

Apply set loads during torque testing, particularly suitable for child-resistant closures

Interchangeable intelligent torque cells

Measure from a few mN.m up to 6 N.m

Measure closure torque to the highest accuracy down to very low values

The Helixa is designed for precision closure design applications, where torque forces may be very small and where accuracy is paramount. Interchangeable torque cells range from 0.1 N.m to 6 N.m capacity.

Precision alignment

Precise user-adjustment of axial alignment ensures accuracy of measurement of very low closure torques

The drive spindle can be user-aligned for precise concentricity with the intelligent torque cell for optimum accuracy, and repeatability, adjustable to each fixture combination. Essential when testing at extremely low torque.

Axial loading for CRCs

Apply axial loading to push down CRC push and turn caps

Load tray for applying a predefined axial load e.g. when push-off twist testing child-resistant closures.

Counterbalance fixtures

Torque measurement and pass or fail criteria are clearly displayed

Counterbalance capability for eliminating the weight of a grip being applied to a sample. Significant when testing precise torque at low forces.

Software: Emperor^TM Torque

Create test programs, perform calculations, and display closure torque measurement graphs

Helixa-i is controlled by Mecmesin’s powerful Emperor™ software, with full sophisticated programming and results calculation, and user-profiled reporting and exporting facilities
Helixa-xt is controlled by Emperor-xt, designed especially for intuitive touch-screen use requiring minimal training for repetitive use. It also has easy-to-use results calculation, reporting and exporting, and can run full Emperor programs created on PC.
