Digital Projector JTC300
JTC300 digital projector is a kind of optical measure instrument to measure geometrical elements of tested object in the method of coordinate measuring and figure comparative measuring. It is direct, precise and effective. By the way of transmission and reflection illuminating, it can measure length, angle, figuration and surface of tested parts, especially suitable for examining small or composite parts, such as horologe component, templet, die, knife, etc. Projector is one of common-use instruments in factory, mine, enterprise, measure room, senior academy, and science research. It is equipped with data output interface to contact to computer to carry on corresponding planar measuring program, further convenient to calculate measured data and enlarging use range.
