SONIC SAFETY SERVICES experienced staff can certify the calibration
of your spirometer and syringe calibration , regardless of manufacturer.
Sonic Safety Services staff can repair and support those spirometry
products we distribute for NDD Medical Technologies, Tyco / Healthcare
(formerly Puritan - Bennet), and OHD. While Sonic can do some repairs to
other manufacturers products, most modern spirometers can only be
repaired by the manufacturer or their authorized representatives.
