Fingertip Pulse Oximeter

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. Press the switch button once.

The LCD digital display will show:

• Pulse intensity by a single column bar graph
• Pulse rate as numbers
• SpO2 (pulse oxygen saturation %) as numbers

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

The 3907 Pulse Oximeter is a similar device but the display includes a graphical representation of pulse wave (line or bar graph). 

SpO2 measuring range: 35 to 99%
Pulse rate measuring range: 30 bpm to 250 bpm.
Pulse intensity: columniation display

Power requirements: 2 x 1.5 V AAA alkaline batteries (adaptable range: DC 2.6 V to 3.6 V)
Operating current: less than 20 mA
Low voltage warning will be indicated in the visual display when battery voltage is so low.
Automatic power off when no finger for longer than 8 seconds.

Display: Pulse: 3-digit and LCD digital display (resolution 1 bpm); SpO2: 2-digit and LCD digital display (resolution 1%); Pulse intensity: LCD bar-graph display

Safety Class: Type BF
Optical sensor: Red light (wavelength 660 nm), Infrared (wavelength 880 nm)

Dimensions: 57 (L) x 31 (W) x 32 (H) mm
Weight: about 50 g (with batteries)
