SPTM-11B Digital Universal Toolmaker's Microscope
The SPTM-11B Digital Universal Toolmaker's Microscope is a high-precision measuring device. It accurately measures external screw-thread parameters (intermediate/coarse/minor diameters, pitch, tooth-form semi-angle), gear hobber specs (lead, saw-shaped angle, tooth profile angle), form/location errors (e.g., position degree on circuit boards, key slot symmetry), and various shaped parts. Equipped with a precision grating scale, digital readout, and micro-printer, it enables easy measurement and data output. Multiple eyepieces/objectives ensure a wide field of view and clear imaging.
Key specs: X/Y ranges 200/100mm, resolution 0.0002mm, accuracy (1+L/100)μm, ±12° angle tilt, 24V 150W halogen lighting. Three objectives (1X/3X/5X) with total magnifications 10X/30X/50X adapt to diverse needs.
