The Triton331 from LaserLinc Inc., Fairborn, OH, is a noncontact laser scan micrometer that can make 12,000 measurements per second (4000 per axis). The higher scan rate enables detection of shorter-length flaws and accurate measurement of hexagonal or other product shapes that incur oscillation, as well as measurements of nonconstant diameter products, such as corrugated tubing. The device links via the TLAser400 micrometer interface card to a PC running TotalVu data processing/measurement software. You can also use the gauge with the company's Lobex system for inprocess lobing measurement.
