Spectra GL422N Dual Grade Laser Level

Description

Long Range, High Accuracy, Dual Grade Laser level.

High performance grade laser with superior grade, level and vertical plane capabilities. The required slope grade is entered via the keypad on the instrument or optional remote control, and is displayed on the LCD panel.

The GL422N Grade Laser can also self-plumb in the vertical plane, for applications such as anchor bolt installation and curtain walling.

To avoid interference with any other laser crews on site, or for safety reasons, the laser beam can be electronically blanked out on up to any three sides of the instrument.

The Spectra GL422N can be used with any Spectra Precision laser receiver. it is particularly suited for use with the larger machine mounted laser receivers for digging or grading operations, whereby the driver can check the grade without leaving the cab.

Automatic Grade Match

The Spectra GL422N Laser Level can be used with the Spectra HL760 or CR700 radio linked receiver to very easily enable automatic grade matching. To match a grade the HL760 or CR700 receiver is simply held at the required height and the laser will slope up or down to seek the receiver. When the laser strikes the receiver it will lock the grade at that slope, and the operator can then work across the site following the preset grade. Grade match is very useful for matching the laser to the grade of existing drains and land form.
