This is a very decent BRAND NEW, Professional Physician Otoscope-Ophthalmoscope Diagnostic Set with CASE. It is made from chrome plated brass and is sturdy and built to last for repeated use in a clinic. This unit makes use of a variable light intensity rheostat type switch that delivers an increasing light intensity through the otoscope and ophthalmoscope as you rotate the switch. The bright 3.2 Volt Halogen lamp is powered by 2 standard C sized alkaline batteries.
IMPORTANT: The instrument handle utilizes a bayonet luer-locking mechanism for changing the instrument heads instead of a pin and small screw that can strip or wear out over time. The heart of any otoscope is it's lens. Our otoscope lens is optical quality and made from glass and specially coated to help resist scratches. Our lens slides out of the way for foreign body removal or cleaning. Our otoscope contains a metal insufflation outlet and insufflation bulbs are available for it on our website and on Amazon. The otoscope works with with disposable specula which is a very important consideration if you will be using the otoscope in a clinical environment or concerned about sanitary issues going from one ear canal to another. The professional model ophthalmoscope contains a complete set of lens from -25 to +40 diopters. It is basic in design and doesn't have all the bells in whistles of a Welch Allyn but it gives a good view of the retina.
