Classify type of measure instrument, 19JC nearly contains all measures of testing geometry. With complete function, high precision, convenient operation and durability, this instrument is a 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.
