TOPCON ROTARI LASER LEVEL, RL-H4C, TOPCON RLH4C

onstruction Laser Topcon RL-H4C, RL-H4C Long-Range Self-Leveling Construction Laser RL-H4C Wide Working Range for All Type of Projects High Accuracy 10 ( 1.5mm@ 30m, 1/ 16in.@ ft.) Easy Operation Slope Matching Capability 3 Power Sources h/ 60h Long Battery Life* Large Dual Handles IP66 Dust/ Water Protection LS-80L Long-range Sensor Stackable Carrying Case * hours with alkaline batteries, 60 hours with Ni-MH rechargeable battery 800m ( 2, 620ft.) Working Diameter 10 Arc-seconds Accuracy construction image The RL-H4C provides horizontal accuracy of 10 arc-seconds ( 1.5mm@ 30m, 1/ 16in. @ ft.) across the 800m ( 2, 620ft.) area in diameter. This is the widest working range in its class. General construction projects grading, excavating, concrete work for foundation and footing, and other exterior works are perfect applications for the RL-H4C.
