The SP-100 serves optometry practices, ophthalmology clinics, and eye departments that record central corneal thickness during an examination. A rechargeable battery and a 530 g weight let one unit move between examination rooms, and the printout and serial export put each result into the patient record.

Optometrists, ophthalmologists, orthoptists and ophthalmic technicians operate it by hand. The operator presses the probe to the cornea with a fresh disposable tip, and a tone guides the measurement, so the operator keeps watching the eye while the unit confirms each reading. The probe calibrates itself at power-on, so the unit is ready for the first patient as soon as it starts. LED illumination lights the 2.7-inch display so you can read values in the exam room.

The unit stores eight readings, and the display shows the average, minimum, or last measurement. Where a thickness value feeds a pressure assessment, the built-in IOP calculation corrected for central corneal thickness sits beside the reading. The built-in thermal printer prints results with the patient ID, name, and measurement date. The 20 MHz probe covers 150 to 1200 µm with ±5 µm accuracy, and the ultrasound velocity is set between 1400 and 2000 m/s from a default of 1640 m/s.

Clinics that keep electronic records use the RS-232C serial terminal to enter patient data and export measurement data, and TOMEY Link integration supports electronic medical records. The unit runs for about 4 hours on battery and measures while charging, so charging doesn't interrupt a session.

A fresh tip for every patient

Fit a disposable tip to the probe for each patient. Each reading therefore starts with a clean tip, and the operator handles only one component between exams.

A probe that calibrates itself

The probe calibrates itself automatically at power-on. The unit is ready as soon as it starts, and it ships with a test piece.

Measurement guided by tone

A tone guides the measurement, so the operator keeps watching the eye while the unit confirms each reading.

Eight readings with three views

Eight readings stay in memory, with average, minimum and last-measurement options. The operator selects the value that goes on the record.

IOP corrected for central corneal thickness

The built-in IOP calculation uses the central corneal thickness reading. The corrected value sits beside the thickness in the same unit.

A printout at the unit

The built-in thermal printer prints in Standard and Simple modes. The printout includes the patient ID, name, and measurement date, and the unit ships with three paper rolls.

Cordless use for about 4 hours

The rechargeable battery gives about 4 hours of continuous operation. The unit measures while charging, so charging does not interrupt a session.

Data export through RS-232C

Enter patient data and export measurement data through the serial terminal. TOMEY Link integration supports electronic medical records.

A 530 g handheld body

The unit weighs 530 g and measures 207 × 118 × 59 mm. It fits in one hand, and it comes with a carrying bag.

Central corneal thickness from 150 to 1200 µm

The measuring range runs from 150 to 1200 µm, shown in 1 µm steps. Accuracy is ±5 µm.

Ultrasound time of flight

Thickness is calculated as (ultrasound velocity × transmission time)/2. The probe works at 20 MHz ±20%.

Selectable ultrasound velocity

Velocity ranges from 1400 to 2000 m/s, with a default of 1640 m/s.

Disposable probe tip

A disposable tip fits the probe for each patient. The probe, its cap and its case ship together.

Automatic calibration at power-on

The probe calibrates itself automatically each time the unit starts. A test piece ships with the unit.

Tone-assisted measurement

A tone guides the measurement, so the operator does not need to look at the display. Each confirmed reading appears on the screen.

Eight-reading memory

The unit stores eight readings, with average, minimum, and last-measurement options. Each option is shown on the display.

Built-in IOP calculation

An IOP value corrected for central corneal thickness is calculated in the unit.

2.7-inch dot matrix display

The 2.7-inch LCD is LED-illuminated and offers an extended data display view.

Thermal printer modes

The built-in thermal printer prints in Standard and Simple modes. The unit ships with three paper rolls, with one installed.

Printout content

The printout shows the patient ID, name and measurement date along with the readings. It stays with the record at the end of the exam.

RS-232C serial terminal

The terminal enters patient data and exports measurement data, and it also receives data. A cap covers it when it is not in use.

TOMEY Link integration

TOMEY Link supports electronic medical records. Measurement data moves from the SP-100 into the record system.

Rechargeable battery

The internal rechargeable battery gives about 4 hours of continuous operation. The unit measures while it charges.

AC adapter

The AC adapter accepts 100–240 V at 50/60 Hz and includes a cord. It powers the unit and charges the battery.

Automatic power-off

On battery alone, the unit switches itself off after three minutes of inactivity.

The SP-100 suits optometry practices and eye clinics that want central corneal thickness from a handheld unit that moves between rooms. A fresh disposable tip for each patient, a self-calibrating probe, and a tone that guides the measurement make the routine quick and consistent. The built-in IOP calculation, thermal printer, and serial export put results on paper and in the record without extra equipment. It ships with a test piece, three paper rolls, and a carrying bag, and it has a measuring range of 150 to 1200 µm with ±5 µm accuracy. It works best as a battery-powered unit, running for about 4 hours at 530 g.
