On a gage specified to a 2 µm error limit, thermal drift is a first-order concern rather than a footnote.\u003c\/p\u003e\n\u003ch2\u003eMeasurement and Operation\u003c\/h2\u003e\n\u003cp\u003eWith a specified error limit of 2 µm and repeatability of 0.5 µm across an 18–50 mm range and 115 mm measuring depth, the 844 N suits inspection tasks where a .0005\" shop gage cannot resolve the tolerance. The modular measuring system allows the platform to be configured for specific applications.\u003c\/p\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cp\u003ePrecision inspection and calibration environments — aerospace, medical, bearing and advanced manufacturing work where bore tolerances are held in microns.\u003c\/p\u003e","brand":"WESTport Corp.","offers":[{"title":"Default Title","offer_id":51277128007716,"sku":"4474000","price":0.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2546\/6268\/files\/MAHR_MARAMETER_844_N_SELF-CENTERING_BORE_GAGE_Model_Marameter_844_N.png?v=1786998964","url":"https:\/\/westportcorp.com\/products\/mahr-marameter-844-n-self-centering-bore-gage","provider":"WESTport","version":"1.0","type":"link"}
