AT-2 Applanation Tonometer

Z-type applanation tonometer exclusively for use with 2ZL/4ZL

Based on Goldmann applanation tonometry and designed for use with TAKAGI slit lamps, the AT-2 (Z-type) provide rapid, safe, and accurate intraocular pressure (IOP) measurement required for the diagnosis of such conditions as glaucoma, ocular hypertension, and retinal detachment.

AT-2 conform to international standard ISO 8612:2009, which sets out requirements concerning accuracy and reliability of the measurements of applanation tonometers.

Accessories

  • Calibrator(check weight/check weight holder) is included for inspection to ensure appropriate pressurisation.
  • TB2 Tonometer Base (option) is required to install AT-2 to 4ZL and 2ZL slit lamp.
  • S12-18 Measuring Prism (included as standard)

 

Features

AT-2 is finished in the same colour as the slit lamp to give a sense of uniformity when installed. Optional tonometer base TB2 is required for installation.

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.
