Vo2Master Pro
The first simply wearable VO2 analyzer
No backpacks, cables, or hoses. No calibration syringes or gas tanks. Validated against the gold-standard.Free mobile application for guided testing.


Lab-Grade Accuracy
Superior data response due to the patented direct gas measurement at the mouth. Shortened sample tubes increase accuracy because the O2 sample is received just after the flow measurement. No need for a sampling pump in a separate box that has to deal with pumping rate and changes in temperature.
Validated against three lung simulators and lab carts. Same high-quality oxygen and flow sensors found in metabolic carts.

Comfortably Wearable
A stabilising five-point harness increases accuracy. At a weight of 200 grams, the device won’t hinder how the athlete performs. Equipment shouldn’t interfere with testing.
There is no longer a need to run with a backpack. Backpacks are meant for books and lunches, not VO2 analyzers.

Guided performance and metabolism testing with the VM Pro. Produce actionable reports for all your clients.
Provides VO2 Max, Training Zones, resting metabolic rate, caloric balance goals, and more.


A Fit for Every Athlete
Easy input of athlete information into a free mobile app.

Store thousands of athlete profiles and tests on your mobile device for quick access and sharing.
Measures flow rates from 2-250L/min and breathing frequencies from 3-80bpm. Having the oxygen sensor situated at the face enables the measurement of faster breathing.
