The Canon TX-20 Full Auto Tonometer easily measures Intraocular Pressure (IOP) allowing doctors to perform simple eye exams efficiently while enhancing patient comfort with a soft air puff. This test is important in evaluating ocular conditions that affect the pressure inside of an eye, such as Glaucoma. Whenever high IOP is detected, a warning message is displayed. The operator can enter any threshold value on the unit?s settings screen to activate the warning system for that value. The TX-20 Tonometer is compact and lightweight at approximately 33 pounds, making it easy to transport and install.

  • Selectable Measurement Modes
    The three-dimensional tracking system of the TX-20 Tonometer features a wide range of movement, so that the examinee's pupil can be detected easily. When in Full Auto mode, the TX-20 Tonometer is a one touch operation for IOP measurement for both eyes. Just press the start button and the unit automatically aligns and measures the intraocular pressure of both eyes. For added flexibility, the TX-20 Tonometer also includes Auto and Manual measurement modes.

  • Soft Air Puff & Position Safety Alert
    For many patients, the only thing significant and worrisome about tonometry is the air puff. The TX-20 Tonometer employs a delicate air puff for patient comfort. When the Safety Alert is set, the TX-20 Tonometer automatically prevents the optical head from making physical contact with the patient.

  • Visual Reliability & Indicators
    When a reading cannot be made, the TX-20 Tonometer display will show a snapshot of the examinee's eye along with the measurement error. The operator will know immediately whether it was an eyelid, eyelash or the eye being out of position that caused the error. The operator will then be informed on the next action to take such as adjusting the chin rest or limiter.

  • External Fixation
    The external fixation is effective for patients with central vision defects and can be activated using the menus on the LCD screen.

  • Compact and Lightweight
    Made for comfort for both the patient and the operator, the TX-20 Tonometer maximizes a small work area with its compact design. At approximately 33 pounds, it comfortably fits on an instrument table with a Canon Non-Mydriatic Retinal Camera (each sold separately.) Keeping the Canon machines next to one another can help to expedite the exam process.

  • Multifunctional Color LCD Monitor
    The 5.7 inch color LCD monitor tilts 40° making the TX-20 Tonometer easy to use whether the operator is sitting or standing. The clear LCD display also includes multi-functional screen buttons allowing the operator to switch menus as needed.

  • Motorized Omni-Directional Joystick
    Aligning patients is made easier using the motorized Omni-directional joystick with a fine focus dial. All positioning may be performed with one hand allowing the other hand to work with the patient, if needed. The top of the joystick button includes the start button, which can immediately be pressed once the patient is properly positioned.

  • Input & Output Modes
    The TX-20 Tonometer provides data output using RS-232C and LAN connections, and data input using USB connections.

  • Printouts & Fast Built-In Printer
    Internal memory provides storage of up to 10 measurements for each eye, listing in the order they were taken, or by reliability. A printout can be setup to automatically print. The front loaded built-in printer includes an auto cutter, making it simple to remove the print-out. New paper rolls (sold separately) can easily be inserted through the feeder.
