(Mahr Federal: Providence, Rhode Island) -- Mahr Federal's Series 300P indicating snap gauges are an excellent choice for highly accurate and reliable measurement results on cylindrical parts with narrow tolerance ranges. The gauges are available in a variety of sizes with measuring capacity increasing in 1" (25 mm) increments up to 9" (229 mm). Series 300P snap gauges can be configured with a number of different indicators and all are fully adjustable with positive position locking at any point within the gauging range.

"Snap gauges are one of the easiest, fastest, most accurate, and economical ways of making OD measurements a shop can employ," says George Schuetz, director of precision gauges for Mahr Federal. "They are very versatile. They can be hand held to measure parts in place, or mounted on bench stands. They can be set up with different indicators for any number of readout configurations. Different anvil styles adapt to a host of measurement conditions. And parts literally snap into place, which assures good part alignment, and along with positive position locking, virtually eliminates operator influence on the measurement."

With a standard dial indicator installed, the measuring range of Mahr Federal Series 300P adjustable snap gauges is 0.020", with a resolution of 0.0001". But 300P snap gauges can also accommodate digital indicators, air probes, or electronic probes using the same standard 3/8" diameter mounting. With an electronic probe and an amplifier, a resolution of 10 µin. can be achieved for tolerance measurements tighter than 0.0005".

Mahr Federal Series 300P snap gauges are available with a wide range of flat, grooved, and blade anvil configurations. Special custom anvils are also available. Large 15.5 mm/0.61" square tungsten carbide anvils provide flat, parallel, long ‑ lasting working surfaces. Anvils can be side-relieved or straddle-milled to provide access in difficult part profiles. Blade widths as narrow as 0.010" (0.25 mm) and depths up to 0.25" (6.35 mm) ensure access in deep, narrow diameters or grooves, even against perpendicular surfaces. All Series 300P snap gauge anvils feature radiused edges to eliminate part marring.
