W.A. Baum Baumanometer Desk Model

True mercury Baumanometer Desk Models do not require routine calibration because they rely on gravity and a physical mercury column. If you have an aneroid model, it must be checked against a mercury column or a calibrated NIST-traceable gauge to ensure the needle points to zero and tracks accurately.

Medical professionals often prefer the W.A. Baum mercury Baumanometer because it is considered the gold standard for clinical accuracy. Unlike digital cuffs, a mercury gravity manometer never drifts out of calibration or suffers from electronic interference.

The classic W.A. Baum Desk Model 300 features a genuine mercury column enclosed in a glass tube. The markings go from 0 to 300 mmHg, providing precise, easily readable measurements for hypertensive patients.

If the glass tube on a Baumanometer breaks, you must immediately evacuate the room and ventilate it to prevent inhaling toxic mercury vapors. You should never use a standard vacuum cleaner; instead, use an approved mercury spill kit or contact a local hazardous waste disposal service.
