Instructions for use




The TSM500 is a combined audiometer and tympanometer. The audiometer can be used for pure tone audiometry and features air- and bone conduction. The tympanometer can be used for measuring the compliance of the tympanic membrane and for ipsi- and contraleteral reflex testing. The TSM500 is therefore the ideal choice for hearing professionals, who need a a user-friendly all-in-one device for audiometry and tympanometry.


Compact and robust design for use in any location

TSM500 is a smart solution for the clinic or on the go. With a solid aluminum casing and resilient probe cable, it is lightweight, compact and robust – ready to withstand daily use and transportation.
