Mitutoyo QM-Height High Performance Height Gages

Mitutoyo QM-Height High Performance Height Gages

QM-Height measures height, height difference (step), inside/outside widths, inside/outside diameters, circle pitch, free-form surface maximum/minimum heights and height difference by scanning measurement*.

Two subdisplay modes display the value from the previous measurements or the value from the zero/origin point. Origin points can also be set from hole centers.

* Scanning measurement stroke is approx. 1 mm above and below from the start point of measurement.

Features:

• Best-in-class accuracy ±(2.4+2.1L/600) μm
• Built-in pneumatic flotation system enables smooth movement over a surface plate. Models without the air suspension feature are also available.
• Simple-to-use control panel enables most measurements to be made with a single keystroke.
• Battery life of 1200 hours in continuous use with four AA batteries, an improvement from 300 hours. (Four commercially available nickel hydride batteries can also be used.)
• Install the optional U-WAVE-T measurement data communication system to output measurement data directly to Excel or SPC software on your PC.

GO/±NG judgment by LED and display symbols

• LEDs indicate tolerance judgment status – green for GO, red for +NG, and orange for -NG. Status is also indicated by corresponding symbols appearing on the display.

Intuitive buttons and layout

• The symbols are for frequently used keys
• Cross-keys provide better operability

Inside/outside diameters, maximum/minimum heights and displacement can be measured using a standard probe

• Besides height measurement, Mitutoyo's proprietary mechanism and firmware enables scanning measurement of inside/outside diameters, maximum/minimum heights, and height differences.

ABSOLUTE encoder maintains the origin

• The electromagnetic induction type ABSOLUTE encoder maintains the origin. There is no need to set the origin after turning on the power. (Except when there is a considerable environmental change.)

New d2 Digimatic and USB outputs

• Digimatic and USB ports are provided as standard. Using the U-WAVE-T measurement data wireless communication system enables instant transmission of measurement data to a PC via wireless communication which reduces manual input errors and improves data reliability and operational efficiency.
• To install U-WAVE-T, separately purchase the optional mounting plate (02AZE990)

Power supply

• Four alkaline AA/LR6 batteries (standard accessories)
• Also operates on four NiMH AA rechargeable batteries
• AC adapter (packages available with or without AC adapter)
• 1200 hours of battery life in continuous use

Probe elevation wheel

• Used for measurement, allowing fine or coarse adjustment of probe height

Air-suspension feature (Available on #64PKA129B and 64PKA130B only.)

• Pressing a button on the grip activates the internal air pump. The base rises on a cushion of air and is able to be moved smoothly over the surface plate.
• Note: Measurements should not be made while this function is in use as it will cause measurement error.

Standard Accessories:

• 12AAA715 - Probe Diameter Calibration Block
• 05HZA148 - ø5 mm Stepped Probe
• Alkaline batteries x 4 (AA/LR6)

Specifications:

*1 - The indication accuracy and repeatability represent the values obtained from the height measurement of a flat surface using the standard holder with ø5 ball contact point. 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 (MLH-521) and Mu-checker (M-551).

*3 - Requires special communication driver and software. Consult your local Mitutoyo Sales Office for details. These can be downloaded from the Mitutoyo web site.

*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.
