MIC-19JC Universal Tool Microscope

 19JC Universal Tool Microscope

Classify type of measuring instrument universal tool microscope 19JC nearly contains all measures of testing geometry. With complete function, high precision, convenient operation and durability, this instrument is normal equipment in precise machinery field, effective testing gist for measure & examination dept., and right hand of science research and teaching field.

Adopting grating subdivision and digital technology, 19JC has the characters of direct reading and good consistency, which greatly improves work efficiency and further enlarge use range.

Digital-display device of this instrument has data output interface, which may be extended to contact with planar data gather and computer measure operating system to upgrade as 19JPC microcomputer-type all-purpose tool microscope.

Universal Tool Microscope (Digital display type) 19JC is projection of the 19JA million workers improved significantly, the use of sub-gratings and digital technology, intuitive readings and consistency with good characteristics such as increased efficiency, to further expand the scope of the use.

Instrument Digital Interface data output table can be extended to connect two-dimensional data acquisition system and computer measurement of the operating system to upgrade its computer-based universal tool microscope 19JPC.
