Quality and value come together in this popular Diagnostic Kit from Riester. The battery handle, which operates on two C batteries (not included), utilizes a bayonet for changing the multiple instrument heads included in the kit. A rheostat controls the level of light intensity provided by the incandescent lamps in the instrument heads.

The Riester Diagnostic Kit includes: a chrome-plated Bent Arm Illuminator for lighting the oral cavity and pharyngeal area; two chrome-plated Laryngeal Mirrors sized 3.0mm and 4.0mm that attach to the Illuminator; a May Ophthalmoscope with lens wheel and correcting lens diopters ranging from -20 to +20; a chrome-plated Nasal Speculum that manually opens and closes within a wide range; a chrome-plated Otoscope with removable cap, three reusable specula, swivel magnifying lens and an outlet for pneumatic testing; a chrome-plated Tongue Blade Holder that uses wooden or plastic tongue blades; and a traditional hard storage case.
