Introduction
The Aircalorisator is a device used for caloric tests in ENG (Electronystagmography) and VNG (Videonystagmography) diagnostics, developed by HOMOTH Medizinelektronik GmbH & Co KG. It is recognized for its ease of use and effectiveness in ENT (Ear, Nose, and Throat) diagnostics worldwide.

Advantages
The device uses air for caloric stimulation, which eliminates the need for water collection and connections. It is suitable for patients with perforated eardrums and can be used in any patient position. The device features a removable ear-joining piece made of skin-friendly rubber to direct airflow safely into the ear canal.
