The ADC Standard 2.5V Diagnostic Instrument Set is a competitively priced, full-featured diagnostic solution designed for reliable daily clinical use. Housed in a durable fitted case, this set delivers essential examination tools for ear and eye assessments while maintaining excellent value for clinics, hospitals, medical offices, and training programs.

The ophthalmoscope head features a precision lens wheel with 24 corrective lenses ranging from –25 to +40 diopters, allowing clinicians to achieve accurate focus and enhanced diagnostic clarity. The otoscope head includes a removable 3X magnifying lens and insufflator fitting, supporting comprehensive ear examinations.

Both instrument heads utilize bayonet-style locking mounts for secure attachment to the battery handle. The set includes Welch Allyn–compatible disposable polypropylene ear specula in 2.75 mm and 4.25 mm sizes, as well as autoclavable polypropylene specula in 2.5 mm, 3.5 mm, and 4.5 mm sizes for reusable options. An adapter is included to ensure compatibility with Welch Allyn or equivalent disposable specula.

Powered by a “C” cell battery handle with a rheostatic on/off switch, this diagnostic set allows smooth light intensity control during examinations. All components are neatly organized in a zippered, scuff- and scratch-resistant case with a fitted insert that cleans easily for long-term use.
