{"product_id":"keeler-r-type-applanation-tonometer","title":"Keeler R Type Applanation Tonometer","description":"Description:The KAT  R-type style applanation tonometer is designed to be used with the H series  slit lamp (tower illumination). The R-type tonometer is fixed allowing for it  to easily swing into and out of position as needed without being removed.  Each of these applanation tonometer units contains a calibration arm and a  re-usable tonometer cone.        The Goldmann principle is considered to be the most prevalent method of  tonometry, as it is the most widely accepted method of determining the  approximate intraocular pressure. The Keeler-manufactured Goldmann tonometers  are designed and built to our exacting standards to give you the accuracy and  quality you expect from a Keeler device.","brand":"Keeler","offers":[{"title":"R-Type","offer_id":47154452791516,"sku":"MBUNIT00024","price":122516.1,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0792\/7060\/9116\/files\/keeler-r-type-applanation-tonometer-6188393.jpg?v=1779438127","url":"https:\/\/globalsurgicals.in\/products\/keeler-r-type-applanation-tonometer","provider":"Global Surgicals","version":"1.0","type":"link"}
