Ultra-thin otoscope

An Ultra-Slimline 3.9mm Probe

At just 3.9mm, the NTE300 otoscope is a whole 1.6mm slimmer than standard 5.5mm otoscopes, allowing greater accessibility to ears of different shapes and sizes, especially children’s ears, because the younger you are the narrower your ear canals are.

The ultra-slim investigative camera combined with the NTE300’s ergonomic body gives an easy and comfortable ear-checking experience every time.
