Spectra Precision HL450 Laserometer Receiver with Digital Readout, 102 mm Beam Reception, IP67 Rugged Housing, Drop-Resistant up to 5 ft, Includes Rod

DIGITAL ELEVATION READOUT: Displays numeric grade deviation on both the front and rear LCDs (±40 mm / ±1.5 in) so you see the grade changes and don’t need to adjust the clamp to find on-grade quickly. LARGE RECEPTION ZONE: Features a 102 mm (4-inch) laser detection height to capture beam rapidly. This is especially useful when working with vertical applications or uneven terrain. Built to IP67 waterproof and dust-proof standards as well as drop-tested for up to 5 ft (1.5 m) onto concrete, reducing downtime from routine accidents. ANTI-STROBE TECHNOLOGY: Patented anti-strobe sensor filters out interference from job-site strobe lights or construction LED hazard lights so your readings stay accurate. TRUSTED SINCE 1965: Spectra Precision has been a pioneer in precision measurement for over five decades, delivering reliable construction tools and laser technology that professionals worldwide depend on for accuracy and durability. The Spectra Precision HL450 Laserometer is a high-performance, digital-grade laser receiver engineered for construction professionals who require precise elevation measurements under rugged job-site conditions. With a clear numeric readout displayed on both front and rear LCD screens, the HL450 shows real-time elevation deviation (±40 mm or ±1.5 inches), allowing users to determine how far away from grade they are without physically moving the receiver. It includes a generously sized 102 mm (4-inch) reception height, which accelerates beam acquisition and improves efficiency when working with elevation changes or vertical structures. To ensure reliability in active, well-lit worksites, the HL450 employs a patented anti-strobe sensor that filters out false signals from construction strobe or LED lighting. Durability is a core design feature: the HL450 is rated to IP67 for water and dust resistance, and its housing survives drops up to 5 feet (1.5 meters) onto concrete, minimizing repair or replacement needs. Powered by two standard AA batteries, the unit can operate continuously for approximately 70 hours before needing replacement. It also includes an automatic 30-minute shut-off to conserve battery life if left idle. The digital readout supports multiple units of measure, including millimeters, centimeters, feet/inches, or fractional inches. This lets operators adapt to the format that best fits their workflow. An audible tone indicates whether the unit is high, low, or level, and settings for accuracy and volume are simple to adjust via one-button access. The HL450 comes with a robust rod clamp, reliable user guide, and is compatible with a wide variety of rotating red-beam lasers across construction and surveying applications. Whether you’re cutting and filling, performing general grading, setting foundations, or aligning forms, this Laserometer offers dependable, precise performance in demanding environments. For engineered accuracy with minimal setup, the Spectra Precision HL450 Laserometer is the top choice professionals trust.
