SPG03 aneroid blood pressure monitor is a leading name in the segment of hospital apparatus and medical calibration tools used to measure blood pressure. The aneroid blood pressure monitor consists of an inflatable cuff wrapped around the arms to restrict the blood flow. The blood pressure is calibrated over a circular dial to hint at the maximum and minimum pressure. Unlike traditional sphygmomanometers, an aneroid blood pressure monitor is completely mercury-free and used with a manual pump and connected to a stethoscope to heartbeats of the heart.

Aneroid blood pressure monitors have a mechanism for calibration checks with reasonable accuracy. Aneroid blood pressure monitor has a provision for mounting on walls and stands to negate the effects of calibration errors. The entire cardiac cycle can be observed using the aneroid blood pressure monitor. The control valve maintains the pressure and the dial reflects the value in mm/hg. Governed by the principle of the auscultatory method, the calibration highlights the anomalies in the five phases associated with cardiac function.
