M-Pulse Finger

The M-Pulse Oximeter from Merlin Medical is the perfect choice for on-the-spot SpO2 and Pulse Rate testing.

The unit’s light weight and small size means it can be easily carried in your pocket. The universal finger clip allows the oximeter to fit a range of finger sizes from paediatric through to adult and the M-Pulse automatically switches off when a finger is removed from the unit for more than 8 seconds.

The M-Pulse’s unique ‘display rotation feature’ allows the user the option of how they would like the information to be shown on screen  – all by a simple touch of a button.  The SpO2, Pulse Rate and Pleth waveform are clearly displayed on a bright OLED screen which has 10 brightness levels to ensure it can be read most lighting conditions.
