Description
Overview
The Welch Allyn Green Series 777 Wall Transformer (77710) is the wall-mounted power base of the GS 777 diagnostic system, without instrument heads. It lets a facility build its own wall setup by choosing the otoscope, ophthalmoscope or other 3.5 V heads separately.
Key Features
- Handle-activated power: lifting a handle from its cradle turns that instrument on and returning it turns it off, which saves energy and lamp life.
- Handle-based rheostats adjust light intensity with one hand.
- Modular coiled cords, 12 ft extended, built for daily exam-room use.
- Choose your own Welch Allyn 3.5 V heads, including wide-view PanOptic or traditional ophthalmoscopes and MacroView or standard otoscopes.
