This caloric stimulator has been created for use in clinics as well as in general physician’s cabinets. Time consuming aspects of the vestibular examination are speeded up by a high degree of automatisation. The rest, count and irrigating period is exactly set and / or can be adjusted by means of the time automatic and operating logic. The exeptional stability of temperature in the water reservoir is rendered possible by use of sophisticated electronic components and the fact that the temperature is measured at several points.
What is especially striking is the temperature measuring by means of a highly sensitive PTC element, which is fitted directly in the distal part of the irrigator handpiece. The temperature indicated thus is exactly the temperature of the irrigator liquid which is applied in the test person’s ear. The sensor cable of the PTC element is carried in the highly flexible water tube.
