Marameter 844 K This family of inside-diameter measuring probes from Mahr can make comparative measurements of precision holes created in the manufacture of a wide variety of end products, including molds and tooling. The 844 K probes are part of a modular system that includes measuring heads, driving needles, measuring holders for indicators or probes, depth extensions, right-angle attachments and setting rings. There are three versions — 844 K for through-bore applications; 844 KC for through-bore applications with sensitive or abrasive surfaces; and 844 KS, for blind-bore applications. The probes can measure diameters from 1mm to 20mm.
What’s new? Major manufacturing upgrades to the product line. Also, the 844 KC comes with a new diamond-like coating, which improves corrosion resistance and wear protection, while also providing a lower-friction surface.
Benefits Faster availability and more capabilities. The new manufacturing processes mean Mahr can supply the probes to customers more quickly. The probes are also backward compatible with existing holders and adapters, so customers can continue using their current accessories. The probes also are self-centering, which reduces operator-induced influences on measurements.
