Testing Rig for Applanation Tonometers

---

PT Series

• The force sensor employed is an optical interferometric device.
• To test a tonometer, the tonometer is driven up against this force sensor with an electromechanical drive.
• Graphic presentation of tonometers‘ buckling-force characteristic curves over their full travels is possible.
• Calibration using standard weights allows tracing its calibration back to national standards.
• Certification by German calibration authorities has been granted.

Technical Data: Measuring range:  0…10 g (100 mN) Resolution: 1 mg (internally 0.1 mg) Standard calibration error of  force sensor : < 0.5 mg Test duration: ≤ 5 min

Applications: Conducting metrological accuracy checks on applanation tonometers in accordance with 11, section 3, MPBetreibV, both in the laboratory and on-site at remote locations Testing tonometers for compliance with the EN ISO 8612 testing standard. Quality control testing during tonometer manufacture.
