The ROMER Absolute Arm.Absolutely Groundbreaking.Portable measuring arms have fundamentally changedmetrology. They make 3D measurement easy and fast.As a result, user productivity is heightened and measurement time is slashed. Where traditional measuringmethods are impractical or impossible manufacturers,in more than 100 countries, rely on ROMER products todeliver the essential information quickly.The ROMER Absolute Arm heralds a new era in thissuccess story. ROMER produces a portable coordinatemeasuring machine which combines the entire experience of the Hexagon Metrology network.ROMER measuring arms stand for maximum mobility in industrial metrology. Carbon fibre tubes ensurestability while maintaining the lowest possible weight.Fully integrated laser scanners make the ROMER Absolute Arm a top performing system for all metrologytasks.Absolute encoders, which assign an absolute valueto each position of the arm, are used for the first timeever in a portable measuring arm. Initialisation is notnecessary. Simply take the measuring arm to the part,switch it on and start measuring.ROMER – absolutely portable CMMs.

The result is themaximum range divided by two.The Volumetric Accuracy Test is the most representative test for volume measurement accuracy. A gageblock with a known and certified length is measuredseveral times throughout the working volume. Thisgage block is installed in different positions and measured depending on multiple approach directions.The result is the maximum deviation of the measuringdistance less the theoretical length.Ambient conditionsWorking temperature:Storage temperature:Relative humidity:Operational elevation:Marks of conformityCE Compliance:YesPower requirementUniversal worldwide voltage110V – 240V10 C – 50 C (32 F – 122 F)-30 – 70 C (-22 F – 158 F)10% – 90% non-condensing0 – 2000 m (0 – 6600 ft)2

The test consists of measuringa matte grey sphere with 5 different arm articulations. In each articulation of the arm the sphere is scanned from 5different directions such that the majority of the sphere is scanned. The result is the maximum 3D center to centerdistance of the 5 spheres.4

ASTM C-1747 More important than compressive strength for pervious (my opinion ) Samples are molded per the standard and then tumbled (LA Abrasion) 500 cycles (no steel shot) Mass loss is measured – lower loss should mean tougher, more durable pervious. Results under 40% mass loss appear to represent good pervious mixes.
