The Baum pocket aneroid is a 300 mmHg portable instrument featuring the calibrated V-Lok system. It's built to agree with our master instruments, which are traceable to the United States National Institute of Standards and Technology. It complies with ANSI/AAMI SP-9 for accuracy and performance (1% full scale 3 mmHg). The unique, high-contrast scale and red pointer increase visibility and reduce parallax error. They are manufactured with a precision low-friction movement and twin pre-seasoned phosphor-bronze diaphragm capsules. The die-cast zinc manometer housing is finished in warm gray-textured baked enamel. The Calibrated V-Lok system immediately indicates whether the correct size cuff is being used. It consists of a non-latex bulb, Air-Flo control valve, non-latex bag and calibrated V-Lok cuff. Hook-and-loop fasteners are used to provide the optimal number of open-close cycles. The center of the bladder is clearly marked on the inner and outer surface of the cuff for correct application on either right or left limb. The cuff is made of tightly woven, urethane-coated, heat-set Dacron polyester. Guarantee: Every Baum aneroid instrument is guaranteed against defects in workmanship and material for a period of one year from date of purchase. This guarantee is invalid when other than genuine W.A. Baum parts are used.
Adult cuff fits a patient arm circumference of 9.8" to 13.8".
This is a first class blood pressure gauge. Every ting about it is professional, and I'm absolutely delighted with it.
