AT900 Tonometer

Be certain your tonometer always measures up.

Frequent calibration is crucial for your practice and your patients.

Schedule Service

Your tonometer is the only part of your slit lamp that makes contact with the patient’s eye and is a highly sensitive precision tool.

To ensure your pressure readings remain diagnostically accurate, calibration checks and expert maintenance must be scheduled regularly.

Even a slight deviation from center can result in inaccurate readings.

Expert calibration means peace of mind.

You may be surprised to learn that tonometers need monthly checks to ensure accuracy. When a tonometer is out of calibration – and nearly half of all tonometers that Haag-Streit On-Site service engineers check are – readings most often drift into the positive range, resulting in higher IOP measurements which can lead to inaccurate diagnoses, and even surgery.

Haag-Streit On-Site service engineers verify calibration as part of each slit lamp tune-up, so you can be confident you’re providing the best possible care and treatment for your patients.

Special repairs

If your tonometer needs repairs, most can be completed on-site. However, there may be issues that require additional work or tools that our service engineers do not travel with. In those instances, your tonometer will be sent to a Haag-Streit office for repairs.

Because we know this downtime can impact your business, we offer a Loaner Program to keep your practice running without interruption.
