Application
φ350 Digital Measuring Projector
JT21
Usages
The instrument can test effectively profile, section and surface shapes of various complex work-pieces, such as templates, punching pieces, cams, gears, forming cutters, mercerizes etc. Owing to its front-inclined projecting screen, so It is also suitable for comparative measurement and test, such as projecting image's portray and observation of work-piece's profile and shape etc. It is widely used in workshops and measuring station of those industries: Machinery, instruments & meters, watches, moulds and electronics and so on.
