Overview for the Spectra GL412 Grade Laser
The Spectra GL412 Grade Laser is a rugged, automatic self-leveling laser that performs level, grade and vertical alignment. This construction rotary laser has a 2,000 foot range and includes an HL700 laser receiver that features a digital readout of elevation and increases the GL412’s operating range up to 2,000 feet.
With grade capability of –10 to +15% on a single axis, the GL412 grade laser self-plumbs in the vertical position to allow bolt installation, form, tilt up, and curtain wall plumbing. It is ideal for agricultural and construction applications with its self-leveling accuracy of 1/16th inch per 100 feet. You can also mount this device on a 5/8-11 tripod thread vertically or horizontally.
Spectra HL700 Laser Detector
The included HL700 Laserometer provides digital readout of elevation that shows exactly how far you are from on-grade and allowing quick elevation checks without moving the rod clamp. Increasing Spectra GL412’s working diameter up to 2,000 feet, this laser receiver has highly visible LED display and features an anti-strobe sensor that stops construction lights from setting off the receiver and makes it easier to identify true laser beam signals. The readout is displayed on dual sided LCDs and selectable units of measure are displayed in millimeter, centimeter, feet, inches or fractional inches.
With a large five-inch reception height, the handheld or rod mounted Spectra HL700 laser detector acquires the beam quickly and makes it easy to stay in the beam. Excavation mode puts more reception height and elevation information above grade for higher utilization in digging and staking applications. It also has a capture function that remotely captures and retains a measurement when the display is difficult to see.
The Spectra Precision GL412 has a mask mode that allows you to turn the laser beam off electronically on up to 3 sides of your choice to eliminate interference with other crews. It also features an electronic leveling vibration filter that dampens vibrations typically experienced on tall tripods, in high winds or on high vibration worksites. Incorporating automatic temperature and grade compensation, this Spectra laser level delivers highly accurate results in any weather or geographical location. It also includes a RC402 radio remote control that gives you full control of the laser from up to 330 feet away.
With an IP66 rating, the GL412 laser level is protected against dust and water jets from any angle and can survive drops of up to three feet high on concrete! This grade slope laser uses four NiMH batteries and works up to 55 hours.
This Spectra grade laser package comes with a HL700 laser receiver, remote control, rod clamp, carrying case, NiMH rechargeable battery pack, charger and a 2-year manufacturer’s warranty.
