D&K Thornstein fixed caliper 3 3/4 double-ended, measures 3.5mm and 4.0mm round handle titanium

Precise Two-Size Measurement in a Compact Titanium Caliper

The D&K Thornstein fixed caliper is a double-ended measuring instrument designed for consistent dimensional assessment in dental and ophthalmic workflows. Its two fixed measuring options, 3.5 mm and 4.0 mm, help professionals select a suitable reference without changing instruments during closely related tasks. The 3 3/4-inch length supports controlled handling in the operative field, while the round titanium handle provides a familiar format for positioning and measurement. As a specialty-neutral caliper, it can support organized measurement steps where a compact, clearly defined instrument is preferred for dental procedures, ophthalmic applications, and related precision work.

Use Cases

• Measure dimensions using the 3.5 mm end during dental instrument-guided assessment.
• Use the 4.0 mm end when the larger fixed measurement is appropriate for the task.
• Compare or verify closely related dimensions without exchanging between separate calipers.
• Support ophthalmic measurement workflows requiring a compact double-ended caliper.
• Use the round handle to position and control the instrument during professional measurement tasks.

Care & Reprocessing

• Clean and reprocess the caliper according to facility protocols and the applicable manufacturer instructions for use.
• Inspect both measuring ends, the fixed construction, and the round handle before use for visible damage, residue, or irregularities.
• Handle the titanium instrument carefully to preserve the defined measuring surfaces and prevent unnecessary contact with other instruments.
• Store in a clean, dry location where the measuring ends are protected from impact or distortion.
