Digital Measuring Profile Projector (JT20A)

JT20A Φ300mm Profile Projector

Usages
This instrument can measure surface and profile of different workpieces with complicated shapes efficiently, such as templates, punched pieces, gears, threads, formed milling cutters etc all kinds of Cutters, tools and parts. It is used widely used in measuring room and workshops for those industries Of machinery-making, instruments, watches etc. 

Features
-Sheet metal is adopted for easy process and light weight. 
-Up and down system of projecting box, adjustment rang of Z coordinate is large. 
-High accurate working stage has a newly & elaborate structure, transmission is very contortable and Portable. 
-Tower turn plate with three lens makes changing magnification convenient, and locating accurate. 
-Large working table, measuring rang together with working distance on object ( three kinds of working Tables are available for option). 
-24V 150W halogen bulb is adopted for transmission & reflection illumination, axial flow fan is used to Cool forcibly. 
-High measuring accuracy and operation efficiency
