Spectra Precision LL400 Self-Leveling Laser

Spectra Precision Laser LL400 Laser Level Sets a New Standard in Rugged Construction and Precise Accuracy. Trimble is pleased to announce the Spectra Precision® Laser LL400 Laser Level. This new fully automatic, self-leveling laser level sets a new standard in rugged reliability, handling a wide variety of general and concrete construction applications.   The easy-to-use LL400 Laser Level features easy, one-button operation for basic leveling and provides reliable, accurate long range measurements, even for machine control applications. The rugged LL400 Laser Level is engineered to withstand a 1 m (3 ft) drop on concrete and a 1.5 m (5 ft) tripod tip-over. This strength, combined with full weatherproofing and dust-proofing results in reduced downtime and lower repair costs. The LL400 features single axis slope mode for accurate slopes on grade. One-person grade matching can be performed at the rod position using an optional RC601 remote control. Choice of Receivers The LL400 offers you a choice of the new HR550 or the CR600 receivers so you can choose the receiver that best fits your application. HR550 Our new LL400 is available with the new HR550 receiver. This new and improved receiver offers some unique features never before available in a laser receiver. Features Benefits Anti-strobe sensor Filters out strobe lights from heavy equipment so you can accurately read on grade without worrying about false readings from peripheral equipment. Rugged, durable over molded housing is able to withstand a 10 ft drop Provides years of dependable use—even under the most severe conditions. Dust - and waterproof Sealed unit operates in all weather conditions; sheet rock dust, or any other foreign material will not harm receiver. Five on-grade sensitivities Lets you select degree of accuracy required for multiple projects with one tool. Dual photocells for wide angle of beam reception Lets you view and operate the control panel regardless of your orientation to the laser transmitter. 15-channel linear display Allows fast, accurate, readings and easy fixed offsets Five-channel green and red LED display Highly visible over long distances at an angle.
