C. E. Johansson Mikrokator Comparator 1µm 510-4

A used C.E. Johansson Mikrokator Comparator  1µm Type 510-4 metric  Shank ø30mm Scale range 60µm, scale division 1µm, Measuring pressure 250gram +/- 35 gram Hard steel tip A Johansson Mikrokator is a mechanical comparator used to obtain mechanical magnification of the difference in length as compared to a standard. A twisted thin metal strip holds a pointer, which shows the reading on a scale. Since there is completely no friction involved in the transfer of movement from the strip to the pointer, it is free from backlash. C.E. Johansson Mikrokator: - Mikrokator can measure graduations as small as 1µm with operational error no larger than ±1% - Construction in the Comparator completely no friction, no backlash and no wear - Adjustment of the lower limit of spindle travel by means of the knurled wheel at the contact tip at the bottom of the stem.  Robust, the measuring spindle can be subjected to excessive loads without affecting accuracy  Weight 0.8Kg
