Spectra HL450 Laserometer W/ Clamp & User Guide

Spectra HL450 Laserometer W/ Clamp Features:

• Digital readout of elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the receiver to get to “on-grade”
• Anti-Strobe Sensor stops construction strobe lights from setting off the receiver, and eliminates phantom strikes for easier identification of true laser beam signals
• Large 4-inch (10.2-cm) reception height allows faster readings by acquiring the beam quickly, and makes it easier to stay in the beam
• Withstands direct drops up to 5 feet (1.5 meters) on to concrete providing less downtime due to damage and service requirements
• Full weather and dust proof design, including the battery compartment assures a longer product life and/or repair costs
• Approximately 60-hour battery life with 2 x AA batteries keeps work going on the jobsite
• Automatic power shutoff (after 30 minutes) reduces annual battery cost
• Includes C45 rod clamp
