- The mobile application produces print-ready assessment reports that can be shared electronically.
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.
Validated against three lung simulators and lab carts.
Same high-quality oxygen and flow sensors found in metabolic carts.
Technical Specifications
Physical Design

Ventilatory Ranges
These ranges are covered by three user pieces; one for RMR, one for CPET, and one for high-flow CPET.
- Ventilation 2-250 Litres per minute
- Tidal Volume 0.25-10 Litres
- Respiratory Frequency 3-80 Breaths per minute
Environmental conditions
- Temperature Range: 17-45o C
- Altitude: Up to 10,000 ft
- Headwind: Headwind decreases accuracy.
- Pressure: 300-1100 mbar (50-110 kPa)
- Humidity: 0-70% Non-Condensing Ambient Air. Avoid testing in the rain. The chart
below specifies the humidity range the analyzer can be used in. For
example, at 17°C the max ambient humidity is 50% Relative Humidity
(RH).
