Osher-Nichamin-Jarvi degree gauge 12.75mm internal diameter 15.0mm outer diameter, an arcuate cut from 20 to 20 on the ring is 20° 40 to 40 is 40°, Thornton titanium handle

Clear Angular Reference with a Controlled Titanium Grip

The Osher-Nichamin-Jarvi degree gauge is designed to provide a practical angular reference during dental and ophthalmic procedures where consistent degree assessment supports careful instrument positioning and operative planning. Its ring incorporates arcuate cuts marked from 20 to 20 for a 20° indication and from 40 to 40 for a 40° indication, helping users identify the intended angular reference directly at the instrument. A 12.75 mm internal diameter and 15.0 mm outer diameter define the gauge profile, while the Thornton titanium handle provides a durable, lightweight grip for controlled handling and repeated visual reference within the operative workflow.

Use Cases

• Reference 20° and 40° angular relationships using the marked arcuate cuts on the ring.
• Support dental procedures requiring a compact degree gauge for positioning or alignment reference.
• Use as an angular reference instrument in ophthalmic workflows where the ring markings are applicable.
• Handle and orient the gauge through the Thornton titanium handle during close procedural work.

Specifications

Care & Handling

• Clean the gauge according to facility protocols and the applicable instrument-care instructions.
• Inspect the ring markings, arcuate cuts, and handle before use for visible damage, distortion, or contamination.
• Handle the ring carefully to preserve the defined internal and outer diameter profile and angular references.
• Store the instrument in a clean, protected location to help prevent damage to its markings and working surfaces.

General use; follow facility protocols.
