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
