Digital Caliper 12″ 300mm

Key Specifications

For a professional-grade 12″ digital caliper, you should expect the following technical standards:

• Resolution: Typically ⁶$0.0005 \text{ inch}$ or ⁷$0.01 \text{ mm}$.⁸

   

• Accuracy: Usually within ⁹$\pm 0.0015 \text{ inch}$ (¹⁰$\pm 0.03 \text{ to } 0.04 \text{ mm}$).¹¹ Note that accuracy slightly decreases as the length of the tool increases.

   

• Material: Hardened stainless steel is preferred to prevent the long beam from flexing, which would ruin the measurement.¹²

   

• IP Rating: Look for IP54 (dust/splash resistant) or IP67 (coolant proof) if you are working around CNC machines or wet environments.¹³
