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, however, uses a superior 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.
Accuracy and reliability
Maintain accurate blood pressure readings with lower lifetime cost with gear-free DuraShock™ technology. The Gold Series' premium gauge provides unsurpassed reliability in a traditional handheld device.
The Welch Allyn Gold Series DS66 DuraShock™ hand aneroid sphygmomanometer is accurate to ±3 mmHg or 2% of the reading above 200 mmHg. This product will maintain the safety and performance characteristics specified at temperatures ranging from 10º C to 40º C at a relative humidity level not to exceed 90%.
The super shock-resistant device can withstand up to 60° drop (twice the AAMI "Shock Resistant" standard) and remain in calibration. It features jewel movement for long life, laser-engraved dial face for accuracy, and a smooth, trigger-style air release valve and ergonomic design with soft plastic inserts at key touch points for comfort. Its lighter-than-traditional-model weight won't weigh down your lab coat.
