Beurer Pulse Oximeter White is designed for at-home spot checks of spo2 and pulse. A fingertip pulse oximeter for non-invasive SpO2 and pulse measurement with an auto-orienting colour TFT display. Key verified details include blood oxygen: Measures arterial oxygen saturation (SpO2); pulse: Measures pulse rate; and display: Colour TFT display with automatic orientation. This keeps the product focused on the functions Beurer specifies for this model. For everyday ownership, display formats: 4 selectable display formats; pulse display: Graphical pulse wave and pulse bar; and automatic switch-off: Automatic switch-off function. It also suits users who want a compact one-button fingertip device. The PO 35 measures SpO2 and pulse with a colour TFT display and four formats; the PO 45 adds perfusion index measurement and provides seven OLED display formats. That makes it straightforward to assess when these confirmed features are the priority.
