The Gold Standard Goldmann applanation tonometry is the most commonly used tonometer in clinical practice and remains the "gold standard" for tonometry worldwide. It was developed in the 1950s and is based on the Imbert-Fick law that states that the pressure in a sphere filled with fluid and surrounded by an infinitely thin and flexible membrane is measured by the counter-pressure, which just flattens the membrane to a plane.

Digital Display The HT-5000 features a digital display that makes it easy to read, even in a dark room. The unit even offers brightness adjustment. |
LED Indicator An LED indicator below the display lets you know whether the measuring prism is within the allowable range during measurement. It glows red if the tonometer is not in contact with the cornea or if it is too close to the eye. |
Sleep Mode The tonometer extends battery life by turning off automatically after 90 seconds. When you're ready to take another measurement, the HT-5000 provides instantaneous wake-up from sleep mode. |

Ergonomic Design For more comfortable observation, the unit was ergonomically designed with a slanted display to match the angle of the operator's view. |
