What to consider before buying

When choosing a ring gauge (caliper is the common term in this category), consider your precision needs, environment (wet/dusty), and budget. For professional machining, invest in Mitutoyo or Starrett. For light use, Neiko or Fowler offer good value. IP66 rated models are essential for coolant exposure. Always verify the product is listed under 'Industrial & Scientific > Test, Measure & Inspect' to ensure proper categorization.
