The Comprehensive Guide to Dial Calipers in China
Dial calipers are precision measuring instruments widely used across various industries in China. Their accuracy and versatility make them indispensable tools for machinists, mechanics, and woodworkers alike. This guide delves into the intricacies of dial calipers, exploring their technical specifications, types, and applications within the Chinese market. Companies like Wenzhou Sanhe Measuring Instrument Co., LTD (www.shahemeasuring.com) are prominent suppliers.
Understanding Dial Caliper Functionality
A dial caliper operates on a simple yet effective principle. Two jaws, one fixed and one movable, precisely measure the distance between them. The movement is translated to a dial indicator, displaying the measurement with high accuracy. This allows for quick and efficient measurements of internal and external dimensions, depths, and steps. The dial’s design contributes to enhanced readability compared to Vernier calipers. Sinotools (www.sinotools.com) is another significant player in the market.
