Graduated rules can be supplied with accuracies of 1/100 mm (0.0004") over 61 cm (24"). Whittam is capable of manufacturing up to 132" long scale sections which can be joined together to any length. The high accuracy is maintained over longer distances by joining the ends ground for butting within .025 mm (.001"). Our Whittam dials or circular scales are accurate to within 18 arc seconds or .00045" on a 10" diameter. We offer circular divided scales and index rings of up to 137 cm (4í6") in diameter.
