Description
The Kowa HA-2 is a portable handheld applanation tonometer designed for professional measurement of intraocular pressure using the recognized Goldmann prism principle.
Its internal single-spring mechanism allows measurements to be taken in different orientations, making the instrument suitable for seated, reclined or otherwise difficult-to-position patients. This versatility makes it particularly useful for domiciliary visits, bedside examinations, mobile services and as a backup tonometer in ophthalmology practices.
The HA-2 is compact, lightweight and well balanced, weighing approximately 240 g. Its ergonomic design enables one-handed operation, while the movable headrest helps stabilize the instrument during measurement.
An integrated light source permits use under different ambient-light conditions. Illumination is linked to the precision thumb wheel, which provides direct pressure readings without requiring conversion tables. The scale covers 0–60 mmHg in 1 mmHg divisions.
The instrument uses interchangeable standard tonometer prisms. An interchangeable long eyepiece with 3× magnification and other compatible accessories may also be available separately.
