The HA-2 applanation tonometer is an easily adaptable and accurate tool that works on the Goldmann prism principle. Using industry standard tonometer probes, this instrument is ideal for domiciliary situations or as a back-up tonometer and provides pressure readings using the gold standard applanation principle. The internal spring mechanism allows accurate readings of intra-ocular pressure in any orientation, regardless of patient position or posture. The compact and lightweight design allows simple and easy operation and the built-in illumination enables use of the instrument regardless of the lighting conditions. The precision dial provides direct readings of the pressure. A 3x long eyepiece is also available.
