Request InfoHexagon Manufacturing IntelligenceHexagon Metrology Inc. has introduced a new line of Romer Absolute Arms. Besides the previously released six-axis arm for tactile and tube inspection, it includes two seven-axis models. The new touch and laser-scanning measuring arm versions include one with an integrated laser scanner and one with the ability to attach an external laser scanner. They are available in six sizes, from a measuring range of 2 to 4.5 m. The portable arm coordinate measuring machines are flexible tools for quality control. The 3-D measuring arms are used for dimensional verification, alignment for assembly,...See full productRelated content from Photonics MediaPRODUCTSPromoted Content May 2023 IssueOptikos Contract ManufacturingOptikos is ready, bring your next optical product to market.
