Product Name: Auto Rebound Tonometer for Ophthalmology Model NO.: SW-500 Medical Device Regulatory Type: Type 1 Group: All Certification: CE, FDA Type: Digital Tonometer Classification: Tonometer Trademark: new vision Transport Package: Plastic Bag or Cotton Box Specification: CE, FDA, SGS Origin: China HS Code: 90185000 Product Description Rebound-TonometerSW-500With vertical and horizontal two working modes, wireless output print data, the equipment is used to measure intraocular pressure, using the principle of: the probe hits the surfaces of different hardness at a certain speed, has different reaction when the probe rebounds. Be of advantages of high accuracy, portable, without anesthesia, without the cross-infection etc.1. Function1) SW-500 Rebound-Tonometer is a handset device2) The probe has very less contact with patient, avoiding discomfort reaction3) automatic exist function of probe2.
