The Reichert Tonopen is an easy to use, portable, hand held applanation tonometer, which provides fast and accurate IOP readings. The Reichert Tono-Pen XL utilizes micro strain gage technology and a 1.0 mm transducer tip. The Tono-Pen is gently tapped on the cornea to obtain four independent measurements. The tonopen displays an average of the four readings, along with a statistical confidence index, ensuring accurate, repeatable, and reliable results. Sanitized tip covers (Ocufilm
) are used to minimize the risk of cross contamination. The Reichert Tonopen comes with carrying case, one box of tono tip covers
, spare batteries
, and an instructional video. The IOP readings of the Tonopen correlate closely with Goldmann Tonometry.
