Fingertip Pulse Oximeter (Graphical)

The Pulse Oximeter can be used to measure human Haemoglobin Saturation and Heart Rate through a fingertip. Pulse oximetry uses a light emitter with red and infrared LED that shines through a reasonably translucent site with good blood flow e.g. fingertip. Opposite the emitter is a photo detector that receives the light that passes through the measuring site. Easy to operate: Put the test subject’s finger into the rubber cushions of the clip and then clip the finger. Pressing the on switch button while power is on will change the direction, brightness and contents of the LCD display. The LCD digital display will show: Pulse intensity by a single column bar graph Pulse rate as numbers SpO2 (pulse oxygen saturation %) as numbers A graphical representation of pulse wave displayed as a line or bar graph. Supplied with a hanging rope. Requires 2 x 1.5 V AAA batteries.
