Configurable length reference bar for laser trackers
Our 803-MCL Length Reference Kit provides a length for use during laser tracker or scanner jobs. Use it to establish system scale when using single measuring instruments or when bundling multiple instruments together. Or use it to verify system accuracy and stability during a measurement job. Many of our customers shoot a length reference bar at the beginning, middle, and end of a job to gain confidence that nothing moved or changed during the shoot.
The 803-MCL consists of a kit of our metric Invar tubing and connectors, two of our 1.5INV magnetic SMR nests (for a 1.5" SMR), and four 15199 square support feet. SMRs are not included with this kit. The Invar tubing elements are individually NIST-traceable. Invar is an excellent material for this application due to its extreme stability over a wide temperature range.
