Ergonomic tympanometer probes make it easy to feel the seal

MADSEN Zodiac is designed with special focus on the probes and the way you work to make it easier to achieve a seal and feel in control of the entire testing process. The diagnostic probe is especially lightweight – half the weight of other probes. All the probes are comfortable to hold and have fewer parts so they are more reliable and easy to clean and maintain. The unique Dual Probe option enables you to keep the screening probe and the diagnostic probe connected at the same time all the time for fewer interruptions and a smoother workflow. MADSEN Zodiac comes with a calibration and probe check tool and convenient EasyLock probe tips.

Robust, responsive tympanometer puts you in control of the testing process

Gain control of the testing process with features such as:

  • One touch/one function buttons with integrated LED lights
  • Wide color screen that is easy to see from any angle
  • Built-in printer
  • Long, robust cables give you freedom of movement.

In addition, light indicators on the probes tell you which ear you are testing and the status of the test. Audio feedback and probe lights alert you to a broken seal, while the pump resets immediately, minimizing disruption to your test.
