Precimar LINEAR Serie Setting and measuring instrument
EN
LINEAR length measuring instruments from Mahr are ideal for use as a setting and adjusting instrument close to the production area. They offer precision setting of inside and outside comparative measuring instruments, inside micrometers, 2-point bore gages, dial comparator snap gages and many other measuring instruments.
As an infinitely adjustable dimensional standard, the LINEAR is a cost-effective alternative to setting gages, adjustment rings and gage blocks.
Key advantages include the ease of handling, short set-up time and ability to set any dimension whatsoever. A switchable measuring force regulator, for both outside and inside measurements, delivers user-independent measuring results.
  • Base bar made from steel alloy, providing the same thermal behavior as the setting and measuring objects
  • Precision ground and lapped guide rail, non-rusting
  • Glued-on steel scale along entire length of base bar
  • Easy to operate
  • Precision adjustable to 1/10 µm
  • Measured values displayed with MarCheck:
    Display unit with extensive measuring functions, USB connection for printer or stick and USB connection and RS232 interface for transfer to PC
  • A factory calibration or DAkkS/DKD calibration is available for the measuring station.
