kalipers

Kalipers are precision measuring instruments designed to determine linear dimensions of objects with high accuracy, similar in function to calipers. The term is used both as a brand name for a line of caliper-like devices and as a generic shorthand in some industries. Kalipers come in digital, vernier, and dial variants and share the same basic features: external jaws for external measurements, internal jaws for holes or bores, and a depth probe for measuring from a base face.

Most Kalipers are constructed from stainless steel or carbon fiber materials to minimize flex and corrosion. Digital models display measurements on an electronic readout and may offer inch/millimeter switching, data output via USB or Bluetooth, and on/off control. Vernier and dial variants provide mechanical readouts without power. Measurement ranges vary from a few millimeters up to several hundred millimeters; resolutions commonly 0.01 mm (0.0005 in) for digital units, with higher-end devices offering 0.005 mm or 0.001 in. They require calibration and proper handling to maintain accuracy, including zero-setting at a known reference and periodic checks with gauge blocks.

Typical uses include manufacturing quality control, toolmaking, and education, where accurate documentation of part dimensions is essential. Limitations include measurement sensitivity to parallax in non-digital models, jaw misalignment, and damage from improper use. Kalipers complement other metrology tools such as micrometers and coordinate measuring machines, offering fast, mid-range dimensional checks.
