It can be used to objectively measure PEF by tracking day-to-day changes in breathing patterns.  Measurement Range: Full (50-800 L/min) and Low (50-300 L/min)

The device is intended for a single user only.

Three-zone helps patients comply with treatment regimens. The color-coded indicators can be adjusted to delineate a patient's green, yellow, and red zones based on personal best peak flow. Color zones setting up shall be prescribed by your physician.
