Overview for Welch Allyn 777-SM2XXX Diagnostic 777 Green Wall Transformer

The Welch Allyn Green Series 777 Diagnostic Wall Transformer is a wall-mounted device used by healthcare professionals in providing proper examination of patients in a clinic or hospital set-up. This accessible tool comes with Welch Allyn LED Ophthalmoscope and LED Otoscope devices, which are primarily used to view and assess the auditory (ears) and visual (eyes) structures. Easy to reach and comes with high-quality examination devices, the Green Series 777 Diagnostic Wall Transformer can ultimately improve day-to-day clinical practices.


With an improved design, this Wall Transformer offers an energy-efficient usage of the physical exam tools, and provides a simple yet efficient way to undergo consultations. Each handle comes with a rheostat, allowing quick adjustments of the light intensity of the instrument, maximizing the potential of the Welch Allyn medical devices. The transformer includes modular coiled cords and an eight foot power cable, which allows for unrestricted installation. The handles are compatible with any Welch Allyn instrument heads.


The Welch Allyn Coaxial LED Ophthalmoscope has a patented Coaxial Vision System, which provides clear, precise examination of differently-sized pupils, vitreous disorders, and fundus, by eliminating shadows and reflections during viewing. Versatile and reliable, this improved Welch Allyn Ophthalmoscope features 28 lenses with a range of -25 - +40 diopters, 18 possible apertures, and polarizing and colored filters, which help to compensate for refractive errors. 


The PanOptic LED Ophthalmoscope helps in the viewing of the inner part of a patient’s eye, also known as fundus, and its surrounding structures. It has long-lasting LED lamps for efficient illumination, has Durashock Technology for enhanced durability, and can provide a 20x larger viewing area than a typical Ophthalmoscope. Available in Standard model or Plus version that has an additional Quick Eye Alignment Technology feature, helpful in achieving a better patient optic disc alignment during eye exams.


The Macroview LED Otoscope comes with a long-lasting ColorSure LED illumination, has a field of view that is three times larger than a single-lens otoscope, and five times magnification feature that aids in a clearer visual of the ear canal and eardrum during ear exams. This device has a focus-free design, with an extended focal length, ensuring a clear and sharp image for a better ear examination. It can also be used for Pneumatic Otoscopy procedure, assessing the mobility and flexibility of the tympanic membrane through air pressure, since it has a closed system and an airtight seal. You can choose between a Basic LED Otoscope, or the Plus LED Otoscope compatible with the iExaminer feature.

Additional Accessory:


This accessory is compatible with Welch Allyn MacroView Plus LED Otoscope, which provides a more enhanced way to view the auditory structures during clinical examinations. Together with the iExaminer app and an iPhone device, the clinician can easily view, capture, and send clinical images digitally through this innovative accessory. The Wall Transformer (777-PM3XXX-US) has a built-in iExaminer storage on its side.
