AT-1 Applanation Tonometer

R-type applanation tonometer compatible with a wide range of TAKAGI slit lamps

AT-1 is based on Goldmann applanation tonometry and designed for use with TAKAGI slit lamps, the AT-1 (R-type) provides rapid, safe, and accurate intraocular pressure (IOP) measurement required for the diagnosis of such conditions as glaucoma, ocular hypertension, and retinal detachment.

AT-1 conforms to international standard ISO 8612:2009, which sets out requirements concerning accuracy and reliability of the measurements of applanation tonometers.

Compatible with all current TAKAGI slit lamps. An optional tonometer base is required for installation (Please see the table below for information about tonometer bases that are compatible with each slit lamp model).

 

Accessories

  • Check weight & Check weight holder (included as standard)
  • Measuring Prism (included as standard)
  • A Tonometer Base (option) is required to install AT-1.

 

Features

Reusable Measuring Prism

Smart integrated structure reduces risk of infection
Measuring Prism S12-18 features an integrated structure that reduces infection risk. Its environmentally conscious design is ideal for re-use, and enables highly accurate and safe intraocular pressure measurement. Methacrylic resin, one of the hardest and most highly transparent optical-use plastic materials, is used to realise brightness and clarity of observation and to maximise product life.
