Castroviejo Calipers with 0-20mm Scale for Precision Measurement
Provides precise external measurements for small components and materials. These Castroviejo-style calipers feature a smooth, non-locking slide action for quick checks, with a clear scale marked in millimetres from 0 to 20 mm.
Manufactured from surgical-grade stainless steel, the instrument has a highly polished finish that resists corrosion and is easy to clean. Its robust construction means it is fully reusable and can be sterilised in an autoclave, meeting CE and ISO 9001 standards.
Primarily used for:
• Measuring gemstone dimensions and wire gauges in jewellery making.
• Verifying component tolerances in watchmaking and model engineering.
• Small-scale measurement in dental, ophthalmic, or other clinical settings.
