بياكوليس يدوي من ساتا قياس (0-200mm) موديل (GL91502)

It is made from durable stainless steel for rust and corrosion resistance, supports dual metric and imperial readings, includes a locking screw for secure measurements, and comes with an ABS plastic box for storage.

Close the jaws and ensure the 0 mark on the vernier scale aligns with the main scale. Read the main scale for the whole millimeters, then read the vernier scale for the decimal portion to obtain a measurement accurate to 0.02 mm.

Close the jaws fully and verify that the main scale reads zero and the vernier scale aligns with zero. If needed, use the locking screw to secure readings after zeroing.

Use the external measuring jaws for outer dimensions, the internal measuring jaws (the upper jaws) for inner diameters, and extend the depth rod at the end of the caliper to measure depths.

Yes. The caliper supports both metric and imperial units, allowing readings in millimeters or inches depending on the scale you are using.

The caliper comes with a high quality ABS plastic box for protection. There is also an upgrade option to a premium ABS new material box in some listings.

Wipe the caliper with a dry cloth after use, avoid exposure to solvents, store it in its protective box, keep the jaws clean, and periodically check zero and calibration to maintain accuracy.

It's suitable for precision tasks in mechanical engineering, metalworking, woodworking, automotive work, electronics assembly, and hobbyist projects where accurate short-range measurements are needed.

Handle with care to avoid dropping or bending the jaws. Use the jaws and depth rod correctly, and keep fingers away from pinch points. Store it securely to prevent damage.

Reading technique, cleanliness of jaws, jaw alignment, temperature, and calibration status can affect accuracy. Ensure clean jaws, proper alignment, a stable environment, and regular zero checks and calibration where needed.

Yes. Perform a quick zero check with jaws closed and verify the caliper reads zero. For critical tasks, calibrate against known standards or reference gauges and re-check zero after calibration to ensure consistent readings.
