W.A. Baum Baumanometer Wall Model

The aneroid gauge should be checked for accuracy against a mercury column or certified calibration tool at regular intervals, typically every 6 to 12 months. W.A. Baum provides calibration services, and the gauge can be adjusted via a calibration screw if readings drift outside acceptable tolerance.

Yes, the aneroid Baumanometer uses a mechanical gear-and-spring mechanism rather than mercury to measure blood pressure. This makes it compliant with regulations in many countries and institutions that restrict mercury-containing medical devices, while still providing clinical-grade accuracy.

The wall model is compatible with standard Baum-branded cuffs ranging from small adult through large adult and thigh sizes. The tubing connectors are standardized, so any W.A. Baum cuff with the appropriately sized bladder can be attached to the wall unit's inflation system.

The unit should be wall-mounted at approximately eye level for the person taking the reading—typically around 5 feet from the floor. Proper mounting height ensures the gauge dial can be read at a perpendicular angle, avoiding parallax error that could skew measurements.
