Gage Block Comparator


The Pratt & Whitney Labmaster Standard is the ultimate gage block comparator.  Our highest accuracy and automated vertical measuring instrument can measure gage blocks with a press of a button.  Our exclusive digital interferometer measures the dimension of the block by comparing the measurement probe position to the wavelength of a HeNe laser light source, effectively coupling the wavelength of light to the block being measured. Our patented laser path is in-line with the measurement axis to eliminate Abbe offset error.
