Different from other gauge, the Rossmax Digital Gauge’s marker feature ensures the accuracy during the measurement. The Digital Gauge is able to record the Korotkoff sound for measuring systolic / diastolic pressure and then the blood pressure would be displayed on LCD, reducing misdiagnosis resulted from time difference. The digital operation and display design clearly indicates the pressure, heartbeat and deflation rate on the same LCD display. The backlight screen design is convenient for users that need lighting. And the large, clear LCD display is also more user-friendly and is shock and water resistant for professional use.
