The Welch Allyn 767 Diagnostic System is designed to put everything you need for fast, accurate diagnoses at arm's length-and in one convenient modular package. This well designed wall transformer includes two Welch Allyn wall handles (pictured here with 18245
Retinoscope, and 11720
Opthalmoscope not included). The 767 features Optisense- a reliable optical sensor that automatically turns handles on when they are removed from the cradle. Best of all, you can add any Welch Allyn 3.5v instrument to your system by simply attaching the optional Optical Third Module (pictured here left with 41100
Transilluminator not included). Also available is an optional digital clock / pulse timer.
