These are the Stainless 12.5 cm Steel Vernier Slide calipers ideal for education and training.

12.5 cm SS Vernier Slide Calipers (5 Inch)

• Depth Gauge
• Full 12.5 cm Capacity
• Inside and Outside Jaws
• Easy Reading Graduations
• Made in India

• Measurement Capabilities: Most 5-inch calipers can measure outside diameter, inside diameter, depth, and steps.
• Accuracy: Look for models with a precision of 0.02 mm to 0.05 mm for standard workshop use.
• Scale Graduations: Many 5-inch pocket calipers are graduated to read in 32nds and 64ths of an inch for imperial measurements. 

• Material: Stainless steel is the most common for durability and corrosion resistance. Brass is available for non-rusting needs.
• Measurement Types: Most 5-inch models support outside diameter (OD), inside diameter (ID), depth, and step measurements.
• Scale: Dual scales (metric/mm and imperial/inch) are standard on most manual models in India.
• Fine Adjustment: High-end models like Mitutoyo and Insize include a thumb wheel for fine control.

• Vernier Calipers (Analog): These use a sliding manual scale to provide precise measurements.
• Digital Calipers: These feature a digital screen that displays measurements numerically, often allowing you to switch between millimeters and inches.
• Dial Calipers: These use a mechanical dial with a pointer for faster reading compared to a standard vernier scale.
• Material Options: While stainless steel is preferred for durability and rust resistance, lightweight plastic and carbon fiber models are also available for general tasks.
