JZK-302 Fingertip Pulse Oximeter

The JZK-302 Fingertip Pulse Oximeter is a compact non-invasive monitoring device designed to measure blood oxygen saturation (SpO₂) and pulse rate (PR) from the fingertip. It features a clear LED display, simple one-button operation and low power consumption. Its lightweight portable design makes it suitable for use in hospitals, clinics, home-care settings and routine patient monitoring. The JZK-302 is powered by two AAA alkaline batteries and provides quick measurements without invasive procedures. Manufacturer information confirms the JZK-302 model uses an LED display and removable battery power.
