The AccuPen is also available for vets. The AccuPen Vet features our latest one tap - one reading gravity offset technology which provides accurate IOP measurements with less tapping.


The AccuPen’s gravity offset technology provides precise IOP measurements with less calibration compared to otherhandheld tonometers. Micro-strain gauge technology, combined with proprietary algorithm, provides reproducible results.


An ergonomic design combined with sighting lines allows for easy visualization of the cornea, facilitating both centralization and perpendicularity. Contoured molding with large, visible LCD allows the AccuPen to be usedambidextrously and fit comfortably in any size hand.


Eliminates the constant need for “up, down, and around” calibration. Long-lasting lithium battery lasts for four to six months.


The AccuPen only weighs three ounces and comes with a custom, heavy-duty traveling case and lanyard for safe transportation.


The gravity offset technology allows for fast measurements with patients in any position. Frees up valuable office space.
