The AsthmaCheck peak flow meter measures a patient’s peak expiratory flow (PEF) and helps monitor respiratory conditions, such as asthma. Its built-in, three-zone system facilitates patient training and compliance, and allows for flexibility in setting the zones to meet patients’ individual needs. 

The device has an easy-grip handle to direct hands away from the airflow path and features a linear scale from 60 to 810 L/min which measures in increments of 10 L/min. The meter meets ATS standards for accuracy and precision. Designed for single-patient use.
