Bench micrometer

One wire methode

Three wire method

Tool maker microscope It is an ideal measuring instrument for simplifying inspection and precision measurement of diameter, forming tools, gauges as well as template checking of thread and angles. Specially recommended for Technical Institutions.

Observation Tube : Monocular inclined at 30º stand Observation Tube : Monocular inclined at 30º stand. Large and heavy base provides extra overall rigidity to the instruments. Measuring Stage : 150mm x 150mm assembled on ball bearing guides to provide accurate and smooth travel up to 50mm in each direction with the use of guage blocks having micro-head standard 0-25mm, least count .01mm. Rotary Stage : Circular stage is fitted on measuring stage, graduated in to 360º with vernier and lock. Eyepiece Protactor : Graduated in 360º with adjustable vernier reading to 6 Min. is coupled with monocular ocular tube for smooth angle measurement.

Illumination : (i) Sub-stage lamp provides transmitted light from a bottom source providing colimated greem filter Halogen light. (ii) Oblique illuminator with adjustable inclination for surface ilumination of sample with relief structure, is also provided. three seperate knobs for different illumination is provided. Three separate knobs for different illumination os provided with variable light control on the front panel.
