Introducing the NPi-300 Pupillometer System

The state-of-the-art Pupillometer providing objective pupillary size measurement and reactivity as the Neurological Pupil index, NPi

NPi-300 Pupillometer

Completely accurate, reliable and objective pupillary size measurement and reactivity data independent of examiner

Pupil reactivity expressed numerically so that now changes in both pupil size and reactivity can be trended over time, just like other vital signs

Infrared camera, high-precision optics, processor and LED light source

Modern Graphical User Interface (GUI) features simple and intuitive icon-based navigation

Upgraded keypad – easy-to-press buttons designed for fast and simple navigation with or without gloves

Durable, ergonomic design

Industry-best full two-year replacement warranty

An accurate, reliable and objective system that enhances pupillary assessment to assist in detecting cerebral insult, guiding treatment and informing prognosis
