SPECTRA PRECISION GL622N Dual Grade Laser Kit

Description

PRODUCT DESCRIPTION
The SPECTRA PRECISION GL622N is an automatic self-levelling dual-grade rotary laser for site preparation, excavation, concrete work, drainage and alignment. It controls horizontal level, single or dual grade, vertical alignment and 90° layout, giving general and specialty contractors one system for a wide range of sitework applications.
With an operating diameter of approximately 800 m (2,600′) using the included HL760 receiver, one person can establish and check elevations across large jobsites. Automatic Grade Match calculates an unknown existing slope, PlaneLok holds the laser plane at the receiver to help compensate for environmental changes, and Automatic Axis Alignment helps align the laser with the grade hub before slope work begins.

FEATURES
• Automatic self-levelling dual-grade rotary laser
• Controls horizontal level, single grade, dual grade, vertical alignment and 90° layout
• Grade range up to ±25% on either axis, with the maximum range not available on both axes simultaneously
• Approximately 800 m (2,600′) operating diameter with the HL760 receiver
• Levelling accuracy of ±0.5 mm at 10 m or 1/16″ at 100′
• Grade accuracy of ±1.0 mm at 10 m or 1/8″ at 100′
• Automatic Grade Match measures and displays an unknown existing slope
• PlaneLok holds the laser beam at a fixed receiver position
• Automatic Axis Alignment helps align the grade axis with the jobsite hub
• Anti-vibration filter supports stable operation in wind or high-vibration conditions
• Mask Mode blocks the beam on up to three sides to reduce interference and reflections
• Selectable rotation speeds of 300, 600 and 750 RPM
• Approximately ±14° self-levelling range
• Visible 639 nm red laser beam
• Class 2 laser classification
• IP67 dust- and water-resistant construction
• Withstands a 1 m (3′) drop onto concrete or a 1.5 m (5′) tripod tip-over
• Up to 35 hours of operation with the rechargeable NiMH battery pack
• Operating temperature range of -20°C to 50°C
• Horizontal and vertical 5/8″-11 tripod mounting

DUAL-GRADE LASER FOR SITEWORK AND DRAINAGE
Use the GL622N to establish known slopes for drainage, driveways, parking areas and excavation, or use Grade Match to reproduce an existing surface when the precise percentage is not already known.
