The length room is responsible for:

The length room is mainly responsible for the measurement value transmission of measuring instruments in the fields of length, end degree, line pattern, angle (including levelness), scale wheels, bearings, thread parameters, engineering parameters and other fields. In addition, there is a precision measurement room, which is mainly used for the measurement value transmission of standard measuring blocks, ring gauges and plug gauges in the field of engineering parameters. Engineers have rich practical experience and technical capabilities, are proficient in various detection methods, and have the ability and experience to flexibly handle and formulate calibration plans for self-made measuring and inspection tools.
