Stainless Steel Vernier Calipers

This essential measurement tool is available as a single, high-quality configuration suitable for student labs and professional workshops alike.

Features:

• 4-Way Measurement: Capable of measuring external objects (large jaws), internal bores/slots (small top jaws), depths (tail probe), and steps (using the back of the caliper head).
• Dual-Scale Versatility: Includes both metric and imperial graduations, allowing for seamless use in diverse scientific protocols without the need for manual unit conversion.
• Hardened Durability: The stainless steel construction ensures the measuring faces remain flat and true, even after repeated use in demanding environments.
• Manual Precision: Unlike digital calipers, these vernier models require no batteries, making them an ideal "always-ready" tool for field research or remote laboratory sites.

Operational Best Practices:

• Zeroing the Caliper: Before taking a measurement, close the jaws completely and ensure the "0" marks on the main scale and the vernier scale align perfectly. Check for light passing through the jaws; if visible, clean the measuring faces to remove dust or debris.
• Avoiding Parallax Error: When reading the vernier scale, ensure your eye is directly over the line you are reading to prevent skewed measurements.
• Storage: Store the caliper with the jaws slightly open (approx. 1–2 mm). Keeping the jaws tightly locked during storage can lead to stress on the locking mechanism and potential misalignment over time.
• Cleaning: Wipe with a lint-free cloth and a light drop of high-quality instrument oil to maintain the smooth action of the friction ruler.
