GL412N Grade Laser, HL450 Receiver and Case
This Spectra Precision Grade Laser package pairs the Spectra Precision GL412N single grade laser with the HL450 Laser Receiver and accessories in a convenient carry and storage case.
The automatic, self-leveling Spectra Precision® GL412N single grade laser is the most rugged, cost-effective laser that does three jobs—level, grade, and vertical alignment. Even in harsh job site conditions, the GL412N delivers consistently reliable and accurate performance, enabling you to work faster and smarter. The rugged GL412N laser can withstand drops of up to one meter (three feet) onto concrete and tripod tip-overs up to 1.5 meters (five feet). This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.
The Spectra Precision® HL450 Laserometer is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter. The HL450 Laser Receiver features a digital readout of elevation that provides a numeric display of ± 40 mm or ±1.5 inches. The readout is displayed on the large front and rear LCDs and shows exactly how far the elevation is from on-grade. Accurate measurements can be made without moving the rod clamp, saving time, and increasing productivity. The HL450 has a 102 mm (4 inches) reception height, double the typical industry standard, which allows quick acquisition of the laser beam. Also included is a patented anti-strobe sensor that prevents construction lights from setting off the receiver and makes it easier to identify the laser beam signals. The Laserometer is designed to survive the tough construction site conditions. It is completely waterproof and can withstand a drop up to 1.5 meters (5 feet) onto concrete.
