Description

Product Introduction:

The all‑copper, non‑magnetic vernier caliper is crafted entirely from pure copper, offering non‑magnetic properties, non‑conductive behavior, and excellent corrosion resistance. It is specifically designed for use in specialized measurement environments that require non‑magnetic, anti‑magnetic, and corrosion‑resistant performance. This product provides four‑function measurement capabilities—external diameter, internal diameter, step, and depth—with clear graduations, intuitive readings, a robust and durable construction, and a comfortable grip. Because copper itself does not generate or become magnetized, it is ideally suited for applications in strong magnetic fields, near precision instruments, medical equipment, and non‑magnetic inspection of molds.

Product Applications:

Suitable for a variety of workshop environments. With excellent overall rigidity, stable accuracy, and a comfortable grip, it is a commonly used basic measuring tool in industries such as machining, mold making, hardware, and automotive repair.

The reading principle of a vernier caliper:

The reading mechanism of a vernier caliper consists of two parts: the main scale and the vernier scale. When the movable jaws are brought into contact with the fixed jaws, the “0” mark on the vernier scale aligns with the “0” mark on the main scale, at which point the distance between the jaws is zero. As the slide is moved to the left to a specific position, the distance between the fixed and movable jaws corresponds to the measured dimension of the part. The integer portion of the dimension can be read from the main‑scale graduations to the right of the vernier’s zero line, while the fractional part—less than 1 mm—can be determined by reading the vernier scale.

Reading method for a vernier caliper:

The reading of a vernier caliper consists of the integer part in millimeters and the decimal fraction in millimeters. The method for taking the reading is as follows:

(1) Integer part: Starting from the first graduation line on the main scale to the left of the vernier zero mark, read the integer portion in millimeters.

(2) Decimal part: The decimal portion in millimeters is obtained by multiplying the number of divisions on the vernier scale that align with a particular mark on the main scale by the instrument’s least count. If no vernier division exactly coincides with a main‑scale mark, and the reading falls between two adjacent marks—greater than one value but less than another—the average of the corresponding least‑count increments may be used.

(3) Determine the measurement value by addition: Add the integer part of the millimeter reading to the decimal portion of the millimeter reading; the sum is the measured dimension of the workpiece.
