The 50B Finger Pulse Oximeter is the perfect choice for on-the-spot SpO2 and Pulse Rate testing. The unit's lightweight and small size means it can be easily carried in your pocket.

LCD Display can be seen even in low ambient light levels. CE Certified, the unit conforms to UK and EC Medical Safety Requirements. (Medical Directive 93/94/EEC) CE 0123
