Built from the ground up with hearing professionals, the Madsen® Zodiac tympanometer supports screening, diagnostic, and clinical tympanometry as well as comprehensive immittance testing. With the Gen 2 probes, it is a preferred choice for middle ear assessment in audiology and ENT clinics. with the new Gen 2 probes is the preferred choice for immittance testing.
Robust and easy to use under all testing conditions, the Madsen Zodiac integrates seamlessly into clinical workflows, supporting reliable tympanometry, acoustic reflex testing, and Eustachian Tube Function (ETF) assessment across patient populations.
Madsen Zodiac tympanometer is available in three versions to support different clinical needs:
Each version is available as a stand-alone tympanometer or a PC-based tympanometry system.
Clinical application
Madsen Zodiac supports a comprehensive range of immittance tests across screening, diagnostic, and clinical tympanometry, including:
Gen 2 probes
Tympanometry probes frequently encounter fluid and cerumen build-up, which can affect performance over time.
The electronics in the Gen 2 probes are positioned further away from the probe tip, protecting measurement accuracy during tympanometry and acoustic reflex testing, even under frequent cleaning.
The Gen 2 probes are compatible with all Quick Check, Diagnostic, and Clinical Madsen Zodiac configurations and are supplied as standard with all new systems, they are also available separately as upgrades for current Madsen Zodiac users.
Designed as a dedicated tympanometer, whether conducting routine tympanograms or advanced diagnostic and clinical testing, clinicians can rely on accurate and repeatable tympanometry results.
Built on decades of experience in immittance testing, Madsen Zodiac combines proven technology with advanced diagnostic and clinical functionality to support confident clinical decision-making.
Robust and reliable, this tympanometer supports efficient workflows and delivers consistent performance in high-volume audiology and ENT environments
Dual Probe™
Madsen Zodiac is the only tympanometer offering Dual Probe™ functionality, allowing screening, diagnostic, and clinical probes to remain connected simultaneously. Clinicians can switch between quick tympanometry and comprehensive immittance testing without interrupting workflow.
Fast testing, long cables, and 1000 Hz probe tone support make the Gen 2 Quick Check probe ideal for pediatric tympanometry and infant middle ear assessment, where accurate results on the first attempt are essential.
When used with Otosuite audiometry software, Madsen Zodiac integrates with other Natus Sensory hearing assessment and fitting systems, supporting a streamlined patient journey from tympanometry to diagnostic audiometry and hearing aid fitting.
