Consistent measurement results

Established for over 50 years, Perkins is synonymous with being the ‘gold-standard’ in hand-held applanation tonometers. The Perkins Mk3 hand-held applanation tonometer provides the same proven accuracy as other clinically-trusted Haag-Streit manufactured tonometers.

Ergonomic design

Clement Clarke originally developed the popular Perkins tonometer during the 1970s. Over time, it has been updated and improved, creating an ergonomic design, as well as giving the instrument a longer-lasting battery and enhanced internal LED illumination.

Improved LED illumination

The innovative built-in LED illumination produces an enhanced image of the tonometer mires, permitting use regardless of ambient lighting conditions. It also produces lower operating temperatures, giving greater comfort to both the operator and the patient.

Longer-lasting battery

The Perkins Mk3 hand-held applanation tonometer contains a long-lasting integral rechargeable battery. In conjunction with the enhanced LED illumination, less energy is required and increased operating times are achieved.

Tonogrip prism holder

The new easy-to-use ‘Tonogrip’ prism holder allows for straightforward placement of both sterilised Goldmann reusable prisms and Tonosafe disposable prisms.
