| The MA 27's dependability
has made it a favorite of hearing professionals for years. Rugged,
all-in-one housing and reliable engineering means it's the audiometer you
can count on. |
| Carefully engineered for
accuracy |
| State-of-the-art
audiometric circuitry ensures accurate, quick test results. Change to
tone, pulse or warble by simply pressing a button. Large, fingertip
control knobs provide access to a full range of frequencies and hearing
levels. |
| Fast and easy to
transport |
| The rigid, yet
lightweight case with built-in handle and storage compartment not only
protects the audiometer, but allows you to pick-up-and-go in a hurry.
Ample storage inside the case is allowed for dual TDH39 headphones and
other accessories. |
