subject: High Precision Digital Caliper [print this page] The new Tresna High Precision Digital Caliper provides an extra high resolution of 0.005mm for higher precision use. The clear LCD makes it easy to read. This type of digital caliper is a tool for the most experienced toolmakers and machinists when the higher resolution is needed. High Precision Digital Caliper, whose resolution is 0.005mm, is finer than those regular ones, whose resolution is only 0.01mm, in the aspect of accuracy. Especially when Micrometering is applied, its measuring accuracy will turn out much higher. Its permissible error, which is nearly half of that of regular ones within the same measuring range, makes the measuring more accurate.
