We are offer a refurbished TONOMETER NIDEK NT-4000

Pulse Synchronized IOP Measurement
The NT-4000 incorporates the "Pulse Synchronized" system for reducing
the fluctuation and pursuing more precise measurements.Advanced APC
(Automatic Puff Control) Function
The amount of air pressure for measurements is reduced by more than
10% compared to the conventional model, for the optimum ease-of-use
and patients' comfort.
Expanded Auto-focusing Detection Range
The auto-focusing detection range has been expanded more than 50%
(compared to the conventional model) in the focusing direction, which

Automatic, Semi Automatic, and Manual.
The NIDEK NT-4000 non-contact tonometer includes all of the features
of the NT-2000 model with a "Pulse Synchronized" system for reducing
the fluctuation and pursuing more

precise measurements.The operator can turn on the pulse
synchronization by flipping a switch and then NT-4000 will capture at
the peak of the heartbeat
cycle to eliminate the fluctuations caused by systolic or diastolic
pressures. With this function activated the noise caused by the
heartbeat is eliminated and the true IOP changes can be identified.
