• Best-in-class accuracy ±(2.4+2.1L /600) μm • Built-in air-suspension feature mechanism enables smooth movement over a surface plate. (Lower-cost version AX type without air suspension also available.) • Easy-to-view, simple control panel enables most measurements to be made with a single keystroke. • Eco-friendly product, operable for approximately 1200 hours with four AA alkaline batteries. (Four commercially available nickel hydride batteries can also be used.) • By installing the U-WAVE-T measurement data wireless communication system or USB communication driver in your PC, the optional functions that enhance operability, including output of measurement data to your PC, become available. The USB communication driver can be downloaded from the Mitutoyo website. (Communication software is separately required.)

In the case of diameter, minimum (maximum) value, circle pitch or difference measurement, measuring errors may be larger than the accuracy ratings listed in the table due to variations in measuring force during a scanning measurement, which differs from height measurement. *2 Indicates the value obtained from the measurement of a straight surface placed perpendicular to the the base reference surface using the Lever Head (519-521) and Mu-checker (519-551). *3 Requires special communication driver. Consult your local Mitutoyo Sales Office for details. *4 When using a model with the air-suspension feature, it is advisable to use a JIS 1 class, or higher, surface plate. Using on surfaces with scratches or unevenness may prevent the system operating to the specified performance. *5 The AC adapter cannot be used to recharge rechargeable batteries. *6 Battery life depends on the operating conditions. In particular, it is more economical to use the optional AC adapter to power the instrument if the application requires prolonged use of the air-suspension feature.
