19jc Digital Universal Tool-Maker's Microscope

19JC Digital universal tool-maker's microscope
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, class technical director, calculate the examination according to it and the assistant of the teaching realm.
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 universal tool-maker's microscope.\
