Vernier caliper for general measurement in machining, can measure the internal and external dimensions, depth and step. The precision of the vernier caliper in line with international standards and national standards (metric & inch).

To measure using a vernier caliper, the user first reads the finely marked “fixed” scale (in the diagram). This measure is typically between two of the scale’s smallest graduations. The user then reads the finer vernier scale (see diagram), which measures between the smallest graduations on the fixed scale—providing much greater precision.


Digital caliper is easy to take relative measurements which zero setting, metric and inch system interchange at any position. With data output interface, data can be input to a special printer or a computer via special cable for data processing and printing.

Special function: With data holding, fast display, fast tracing maximum and minimum value during measurements, conversion between relative and absolute measurement and tolerance zone setting.
