SATA ST91513 Digital Caliper

Switching units is quick and simple—press the unit button to toggle between millimeters (mm) and inches (in). The display will update to the chosen unit, and you can switch back at any time.

The caliper supports four modes: external jaws for outside dimensions, internal jaws for inside dimensions, a depth probe for depth measurements, and a step function for measuring steps. Use the external jaws by clamping the object between the main jaws, insert the internal jaws into holes or slots for inside measurements, extend the depth probe from the end for depth measurements, and use the stepped edge to measure steps or offsets.

The zero setting lets you reset the display to zero at any position, enabling relative measurements and quick comparisons. Use it when you want to measure the difference between features, or to set a reference from a specific point before taking additional measurements.

Key specifications include a durable stainless steel body, a high‑resolution digital LCD display for clear readings, multiple measurement modes (external, internal, depth, and step), a zero‑setting function for relative measurements, a locking screw to secure readings, and automatic shut‑off to conserve battery life. It supports both metric and imperial units and is designed for portable, on‑site use.

This caliper is well suited for woodworking, metalworking, automotive work, electronics, and general DIY projects where precise, repeatable measurements are important. It’s handy for checking bore diameters, slot widths, raw material thicknesses, and step heights, among other tasks.

To use it, turn it on and select the measurement mode, take the measurement with the appropriate jaws or depth rod, and use the locking screw to hold a reading if needed. For maintenance, wipe it with a soft cloth after use, keep it dry, store in its protective case, and avoid exposure to harsh chemicals to maintain accuracy and longevity.

Handle with care to avoid dropping or striking the caliper, which can affect accuracy. Keep it clean and dry, use the locking screw to prevent movement during measurement, and avoid applying excessive force on the jaws. Store in a protective case when not in use.

For a direct comparison, you can consider the SATA ST91514 Digital Caliper, which offers similar stainless‑steel construction and four measurement modes: external, internal, depth, and step. It’s available here: https://fepy.com/product/sata-st91514-digital-caliper. Another option is the SATA ST91512 Digital Caliper, which provides comparable functionality at a potentially different price point: https://fepy.com/product/sata-st91512-digital-caliper.

Digital calipers provide direct numeric readings, eliminating parallax errors, offer easy unit switching between metric and imperial, allow zeroing at any position for relative measurements, and give quick, repeatable readings. The locking screw also helps stabilize measurements for accuracy.

Value comes from a combination of build quality (stainless steel durability), feature set (four measurement modes, zero setting, auto‑off, locking screw), ease of use (large LCD, unit switching), and portability. Compare these aspects with other digital calipers on Fepy to gauge which model best fits your budget and project needs.
