How DuraShock™ Technology Works

In traditional aneroid sphygmomanometer design, several delicate gears and springs convert and amplify vertical movement of the pinion to rotational movement to turn the pointer. 

The DuraShock gear-free design uses a single helix spring to directly convert the vertical movement of the pinion to rotation of the pointer without the use of a multi-step gear arrangement.

By creating a gear-free design, the DuraShock has fewer moving parts to provide a gauge which is shock resistant. The DuraShock has been tested and validated to withstand a drop of 76cm onto a hard surface and still remain accurate.

DuraShock is the ONLY aneroid gauge which can meet the AAMI Shock Resistant specification
