Reliable tympanometer for control, confidence and efficiency in immittance testing

New MADSEN® Zodiac is an advanced immittance solution from Otometrics that gives you an easier way to a reliable seal.

Built from the ground up with special focus on the probes, MADSEN Zodiac delivers the control, confidence and efficiency you need to achieve successful outcomes when making middle ear analyses.

Reliable, responsive and easy to use, comes in three versions: 
  • Quick Check 
  • Diagnostic
  • Clinical

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.
