4-Piece Precision Measuring Sets

A complete, single-SKU solution for equipping physics lab stations or individual workstations.

• 1 Micrometer Caliper, 0 - 25 mm x 0.01 mm
• 1 90° Knife Edge Square, 100 mm x 70 mm
• 1 Vernier Caliper, 150 mm x 0.02 mm
• 1 Steel Ruler, 15 cm x 0.5 mm

Features:

• Ultra-Fine Resolution: The Micrometer Caliper allows for extremely precise thickness measurements, ideal for determining the gauge of metal foils or small mechanical parts.
• Versatile Dimensions: The Vernier Caliper features dual jaws for measuring internal and external diameters, as well as a depth probe for blind holes.
• Standardized Alignment: The Knife Edge Square is indispensable for checking the perpendicularity of experimental setups and ensuring 90° precision in fabrication.
• Durable Construction: Instruments are crafted from high-quality metals designed to resist thermal expansion and maintain calibration under standard laboratory conditions.

Usage & Maintenance Tips:

• IMPORTANT! Zeroing Instruments: Before each use, ensure the Micrometer and Vernier Caliper are "zeroed." For the micrometer, use the friction thimble to close the jaws gently—over-tightening can damage the precision threads.
• Storage: To prevent corrosion, wipe each instrument with a clean, dry cloth after use. Store them in a padded case or drawer to prevent the "knife edges" from becoming nicked or dull.
• Calibration: Periodically check your instruments against known gauge blocks to ensure continued accuracy over time.
