Model No: HO-PP-M300

Holmarc manufactures profile projectors in two standard models for general purpose engineering measurements. In the model HO-PP-M300, measurement range is 25 mm x 25 mm along X and Y axes where as in Model HO-PP-M300D, measuring range is 100 mm x 200 mm. Our profile projectors find applications in routine inspection of mechanical, electrical and electronics parts in production floors as well as in laboratories.

Profile projector magnifies and projects size and shape of a work piece on to a fine ground glass with precision. The screen has a 90 degree cross hair lines and is fixed on a 360 degree rotatable ring operated by a knob. The rotating ring is graduated to 360 degree with a vernier resolution of 3 arc minutes. Our profile projectors use multi-layer AR coated tele-centric projection lenses which ensure high transmission with optimal contrast for viewing and measuring complex contours. Linear measurements are taken from precision XY stages fitted with either digital read outs (DRO) or micrometers.

Projection screen brightness is a decisive factor in how easy it is use a profile projector. Our profile projector uses high bright tungsten halide lamp for both contour and surface illumination. The brightness can be adjusted continuously by rotating a knob at the front base. The work piece under inspection is placed on the measuring XY stage. Under proper illumination, a clear image is formed on the screen. The focusing can be done by rotating the knob provided at the front base of the instrument. Measurements are taken from the micrometer or DRO by moving the image with respect to the cross hair line on the screen. Angular measurements can be taken by rotating the screen with respect to the fixed image. The stage is provided with a center hole and transparent glass top for bottom illumination.
