Designed for noncontact distance measurement of hot metal surfaces, the new pulsed laser rangefinder from Riegl USA is available in a range of rugged industrial housings. The LD90-3100 HS/HT features a typical absolute measurement accuracy of ±0.8 in. with 0.1-in. resolution. Additional benefits are a narrow measurement beam, immunity to electromagnetic and acoustic interference, minimal maintenance requirements, and easy on-site installation without the need for calibration.
