TOMEY AUTOREFRACTOR TR-4000

Automatic Refraction Measurements

The TOMEY TR-4000 Auto Refractometer provides highly accurate measurement of patients' refractive error. This measurement is obtained simply by pushing a button. Patient alignment is simple & effortless with the joystick controller. The TR-4000 automatically calculates interpupillary distance (PD) based on the patient's alignment.

Fast & Accurate Measurement

With dual CCD cameras for accurate, reliable & repeatable measurements, the TR-4000 offers a fast (0.3 seconds) measurement time & unique multi-averaging refraction readings.

Data Output

Refraction results are immediately available on-screen & from the system's quiet, built-in, high-speed printer. Results can also be transferred to the office database via the integral RS-232C connection.

The stand-by, or sleep, mode is automatically activated after five or ten minutes(operator selected) of idle time. This reduces power consumption, resulting in operating cost savings & increases the overall lifetime of the TR-4000. Simply push the joystick button to reactivate the device.
