Sokkia Introduced LP31A, LP30A Leveling Lasers

SokkiaintroducedLP31Aand LP30A Leveling Lasers. The LP30A offers a range up to 600 m (2,000 ft) in diameter with an accuracy of 7 arc seconds (1 mm/30 m). The LP31A matches the LP30A feature for feature, differing only in the horizontal accuracy and detectable range. The LP31A’s range is up to 240 m (800 feet) in diameter and has a horizontal accuracy of 10 arc seconds (1.5 mm/30 m). Both the LP30A and the LP31A employ Sokkia’s precision pendulum compensator to ensure horizontal accuracy. Both models are also highly water-resistant in compliance with IPX4. The extended operating duration of the LP30A and LP31A is 90 hours with four D (R20) alkaline batteries and 40 hours with Ni-Cd rechargeable battery BDC39A. The LP30A/31A’s reference beam can be simultaneously picked up by one or more detectors, increasing the flexibility of operation on large projects. (Sokkia, Olathe, Kan.)
