1. Introduction
1.1 Overview
Auto Non Contact Tonometer HNT-7000 is the equipment to provide.The
information of examinee`s Intraocular pressure.
Auto Non contact Tonometer HNT-7000 measured intraocular pressure of
both eye by Full-Auto button.
In particular, when a lot of lights are sensed the moment that compressed air
is separated, prescription about glaucoma is possible by system that convert
time to mmHg intraocular pressure after measure microseconds.
Automatic and passivity compensation function of measurement by cornea
thickness are possible, It supply optimum intraocular pressure information.
1.2 Classificaiton
Classification of product : 2nd Grade Medical Instrument
Resistance against electric shock : Class I (earthed)
Protection class against electric : Type B
