Wide Dioptric Measurement Range 
The ERK-5400 covers an impressive measurement range of -25.00D to +22.00D. 

Corneal Measurement and Contact Lens Base Curve Measurements 
With the ERK-5400, you can measure the size of the cornea and determine contact lens base curve.

Illumination Mode 
The Illumination mode in the ERK-5400 is very helpful in determining ocular health.

Focusing Control Software 

In the event that the operator misfocused while measuring the patient's eyes, the software automatically adjusts the data to produce an accurate measurement result.

Precise Temperature Sensors 
A temperature control chip detects the internal temperature with each measurement to ensure precise data.
