Universal single-axis length measuring unit with MarCheck
Description
LINEAR length measuring instruments from Mahr are ideal for use as setting and adjusting instruments in the manufacturing environment. They allow precise setting of internal and external comparators, internal precision measuring instruments, snap gages with displays and many other measuring instruments. As an infinitely adjustable measurement standard, the LINEAR series is also an economical alternative to setting gages. The simple handling and short measuring time are key advantages. A measuring force control feature can be activated to allow measuring results independent of the user for both internal and external measurements. Based on the steel scale, the LINEAR series ensures reliable measuring results over the entire measuring range. Compatability with national standards means that LINEAR length measuring instruments are DN EN ISO 9000-compliant.
Universal A large number of contacting elements, anvils and clamping devices are available to satisfy all manner of requirements.
Features
Applications
Setting measuring instruments with displays such as the Multimar 844T
Setting two-point internal measuring instruments such as the 844 N
Checking setting standards
Checking calipers
Checking inside micrometers
Measuring cylindrical parts
Measuring internal dimensions and bores etc.
Measured values are dipslayed on the clearly laid out MarCheck digital display which has a large number of measuring functions and an RS 232 interface. This makes it easy to transfer measured values to PCs.
