W.A. Baum Company
William A. Baum, the founder of W.A. Baum saw the importance of accurate blood pressure measurement. He then also saw the imperfections of the equipment being used. He then realized that something needed to be done about this situation, so he invented a product, in 1916, known as the first Baumanometer blood pressure instrument. It was a simple product and the user could verify the accuracy of their blood pressure by simple observation.
Today the Baumanometer is not the only thing they sell, they also created a line of Aneroid instruments individually calibrated to master Baumanometer mercury-gravity manometers traceable to National Institute of Standards and Testing Stethoscopes and a full complement of world class blood pressure inflation system components.
