    Overview for Spectra Precision GL612N-NR GL612N Grade Laser

    The Spectra GL612N is a rugged, automatic self-leveling laser with a working range of up to 2,600 feet. Used in a wide variety of grading, excavating and alignment applications, this construction rotary laser features PlaneLok and Grade Matching for increased accuracy in slope measurement. Featuring single grade capability of ±25%, the GL612N grade laser self-plumbs in the vertical position to allow bolt installation, form, tilt-up, and curtain wall plumbing. It also delivers a self-leveling accuracy of ±1/16th inch, making it ideal for agricultural and construction applications. 

    Allowing the use of multiple lasers on-site, the GL612N features a mask mode that eliminates interference with other crews. Electronic leveling vibration filter reduces vibrations typically experienced on tall tripods, in high winds or on high vibration job sites. Incorporating automatic temperature and grade compensation, this Spectra Precision laser level delivers highly accurate results in any weather or geographical location. This slope laser also comes with the Spectra HL760 laser receiver which provides a digital readout of elevation and features an anti-strobe detector that prevents false readings from site strobe lights.

    With an IP67 rating, the GL612N laser level is protected against dust and water immersion and can even survive a drop of up to three feet on concrete! It features an intuitive keypad and a graphic display. In addition, contractors can mount this single grade laser vertically or horizontally on a 5/8-11 tripod. The Spectra GL612N works up to 35 hours using rechargeable NiMH batteries and approximately 40 hours using alkaline batteries.

    Configuration Options

    The Spectra GL622N has an optional RC602N radio remote control with a backlit display that gives contractors full control of the laser from up to 490 feet away. Please select your preference from the menu above. 

    • GL612N-NR: With HL760 Receiver
    • GL612N: With HL760 Receiver & RC602N Remote Control
         No Cost 5-Year Warranty offers no repair charge for parts and labor of the laser.     
         Shock Proof ensures this construction laser withstands a three feet drop onto concrete.     
         Included Radio Remote control is easier to use because it does not have to be aimed at the laser for it to work. This increases the flexibility of the laser for long-range setups while maintaining outstanding accuracy.
         Fingerprint function filters out other lasers that strike the receiver and only accepts the laser that it is paired with.   
         Grade Match enables contractors to measure an unknown grade value automatically between two elevation points.     
         Dual Axis PlaneLok keeps the laser beam fixed to a receiver in a set position, making it accurate and error-free.     
         90 Degree Layout provides all the references required for a wide variety of interior applications including wall layout and installation, acoustic ceiling installation, point transfer, and tile layout.                             
         Active Temperature Compensation gives accurate, stable results regardless of temperature changes.
