When Diagnosys decided to design a new Electrophysiology instrument they analyzed the current market and came up with a product that meets all the current and hopefully future requirements for electrophysiology testing which they incorporated into the ESPION system.

This system is designed to be small, portable, accurate, easy to use, expandable and incorporates many suggestions and features from leading clinical and research faculties in the UK and the USA.

Incorporating features for both standard ISCEV tests and new research, the ESPION system should be your number one choice in visual testing.
