Philips Respironics Hs755 Personal Best Peak Full Range Flow Meter

Handle: handle converts into a carrying case for ultimate portability and protection. Zones: built-in flexible three-zone management system and easy-to-read numbers. The integrated three-zone asthma management system helps patients comply with treatment regimens. The color-coded indicators (located to the right of the scale) can be adjusted to delineate a patient's green, yellow, and red zones based on personal best peak flow. Ranges: available in full (60-810 l/min) and low (50-390 l/min) ranges. Mouthpiece: safety mouthpieces reduce the risk of cross-contamination during multi-patient screening, and the one-way valve prevents patients from inadvertently breathing in air through their meters during peak expiratory flow rate testing. Life span: accuracy and reproducibility assured for a minimum of two years. Quality assurance: 100% of personal best units are quality-control inspected at the factory before shipment. Warranty: personal best is backed by a one-year unconditional warranty. Any unit performing unsatisfactorily for any reason during this period will be replaced free of charge by respironics.
