Finger Tip Pulse Oximeter JZK-301

The JZK-301 Fingertip Pulse Oximeter is a compact, non-invasive device designed for spot-checking blood oxygen saturation (SpO₂) and pulse rate (PR) through the fingertip. The JZK-301 is suitable for adult patients in home and hospital environments, according to its FDA indications for use. The device features an OLED display, adjustable viewing direction, low-battery indication, alarm functionality and automatic power-off. Published specifications give an SpO₂ measurement range of 0–100% with 1% resolution and a pulse-rate range of 30–250 bpm with 1 bpm resolution.
