The МК6 Urofloumeter records and charts a patient’s pattern of urinary volume and flow. The МК6 system helps physicians in real time assess the mechanics of flow and diagnose abnormalities in voiding patterns (obstructed or restricted flow). The values are displayed, as well as charted, by the computer. The МК6 Uroflowmeter features a high-performance microprocessor and the digital scale (used as the flow sensor) designed to streamline diagnostic uroflow recording.
