RVFM Fingertip Pulse Oximeter

This Pulse Oximeter can be used to measure human Haemoglobin Saturation and Heart Rate through your fingertip! The meter uses a light emitter with red and infrared LED that shines through a reasonably translucent part of your body that has a good blood flow, e.g. your fingertip. Opposite the emitter is a photo detector that receives the light passing through the measuring site. The Oximeter is easy to operate - simply put your finger into the rubber cushions of the clip and then clip the finger. Pressing the switch button once activates the meter.

The LED digital display shows:
• Pulse intensity by a single column bar graph
• Pulse rate as numbers
• SpO₂ (pulse oxygen saturation %) as numbers

Supplied with a hanging rope. Requires 2x 1.5 V, AAA batteries.
