Rotating Laser RL-H3A/H3B

RL-H3A

RL-H3B

The RL-H3A/H3B series is rotating lasers that inherit the features of RL-HA/HB which enjoyed a high reputation because of accurate detection of control positions by automatic leveling, waterproof design and other features. The new series features reinforced basic performance and functions.
Horizontal accuracy particularly is boosted to ±8″ for RL-H3A and ±10″ for RL-H3B for more reliable leveling in interior finishing work, architecture, construction and civil engineering. A higher work efficiency is assured when level sensors are used.

	Higher horizontal accuracy A higher accuracy compared with former models for more dependable leveling.
	Automatic leveling Auto leveling up is accomplished and a horizontal laser beam is emitted simply by installing the laser and turning the power on even if the laser main unit tilts (±3° maximum).
	Three power supply sources (Option for RL-H3B) Three power sources can be used (dry batteries, rechargeable batteries and AC power supply).
	Datum references notified by liquid crystal display and buzzer The level sensor supplied as an accessory notifies the position of laser beam emitted by the laser by a liquid crystal display and buzzer tone.

Rotating Laser RT-5Sa /RT-5Sb

RT-5Sa

	Horizontal accuracy ±5″. An angle detection encoder system and fully automatic leveling mechanism unique to TOPCON assure a uniform measurement accuracy for bulldozer and hydraulic excavator work that requires a high contour accuracy.
	High-gradient settings from -50% to +50% assure quick positioning on a slope. Efficient work by the fully automatic leveling function. Most suitable for machine control of a bull dozer, hydraulic excavator and other equipment.

	The detachable keyboard has a remote control function. Wireless grade setting, auto shut-off, auto alignment, rotation speed change, laser output change and power ON/OFF by remote control.
	Repels splashed water. The unit can be used where water is splashed and it showers. Compliant to JIS C 0920 class IPX6 (Waterproof type)
	Laser beam emission direction can be set electronically to prevent emission of a laser beam in directions other than that set by RT-5S to minimize interference when several level sensors and rotating lasers are used.
	Slope reference directions and gradients are set automatically using a reflection target. Easier and more accurate installation compared with conventional methods that use a scope mounted on the laser main unit.
	RT-5Sa is for dual axes setting and RT-5Sb for single axis setting.

Rotating LaserRL-H1Sa/H2Sa

RL-H1Sa

RL-H2Sa

Level Sensor LS-70A

Level Sensor LS-70B

The RL-H1Sa and H2Sa with a gradient function are new additions to TOPCON's rotating laser RL-H series. For use as normal rotating lasers and more efficient and accurate work is assured in combination with a machine control product, a pride of TOPCON.

	Electronic shutters Keying operation on the laser main unit sets a laser emission range. This prevents malfunctioning on the sensor side when several rotating lasers are used at one work site.
	Long battery operation duration Battery operation duration about twice longer compared with former models. (Operation duration by alkaline batteries: 45 hours) An environmentally friendly nickel-metal hydride rechargeable battery is also used.
	Three power supply sources Three power sources can be used (dry batteries, rechargeable batteries and AC power supply).
	Grade setting Gradients can be set freely within the range of -5% and 10% by key input. The digital display is easy to see and settings can be confirmed easily.
	Wide-range 2-axis tilt sensor (RL-H2Sa) The newly developed wide-range 2-axis tilt sensor directly measures laser main unit tilt and the set gradient, allowing setting of a 2-axis gradient in high accuracy
	Water tightness JIS protection class IPX6 or higher The inside of the main unit is reliably safeguarded against a shower and downpour during work.
