Micrometer High Accuracy

MDH Micrometer High-Accuracy Sub-Micron Digmatic Micrometer
Series 293 
Features
•    Enabling .000005”/ 0.1μm resolution measurement, this micrometer is ideal for customers who need to make highly accurate measurements with a hand-held tool. 
•    A highly rigid frame and high-performance constant-force mechanism* enable more stable measurement, while the clicks emitted while the work piece is being measured assure the operator that measurement is proceeding normally. * Patent pending in Japan, the United States of America, the European Union, and China. 
•    Body heat transferred to the instrument is reduced by a (removable) heat shield, minimizing the error caused by thermal expansion of the frame when performing handheld measurements. 
•    The ABS (absolute) rotary sensor also eliminates the need to perform origin setting each time the power is turned on, letting you start measuring straight away. With no possibility of over speed errors, the High-Accuracy Digimatic Micrometer also delivers a higher level of reliability.
