Wright Peak Flow meter, England, 1980
The Wright Peak Flow Meter measured the flow of air when a person breathed out. Used by physicians to test how well a patient’s lungs were working, the meter could also be used to help diagnose and monitor conditions such as asthma. It could also assess the damaging effects to the health of those working in dangerous trades such as mining. Basil Martin Wright (1912-2001), a bioengineer, invented the meter in 1956. Clement Clarke International made the meter and now manufacture digital and miniature versions.
