Our highest accuracy automated height gage can measure length and thickness with a push of a button. Our exclusive digital interferometer measures the dimension of the specimen by comparing the measurement probe position to the wavelength of a HeNe laser light source, effectively coupling the wavelength of light to the part being measured. Our patented laser path is in-line with the measurement axis to eliminate Abbe offset error. The Labmaster Standard is the ultimate gauge block comparator with many more uses besides gage blocks. This instrument is also widely used with the ball manufacturing and film thickness industry.
