Spectra GL422N Dual Slope Grade Laser
Horizontal / Vertical Red Beam Laser - Rechargeable Batteries |
| GL422N with HL760 Laserometer Receiver and RC402N Remote |
|
|
The automatic, self-leveling Spectra Precision® GL422N dual grade lasers is the most rugged, cost-effective lasers that do three jobs—level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL422N delivers consistently reliable and accurate performance, enabling you to work faster and smarter.
The rugged GL422N lasers can withstand drops of up to three feet onto concrete and tripod tipovers up to five feet. This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.
The GL422N laser system now includes the advanced HL760 Digital Readout (DRO) receiver that provides automatic Grade Match, PlaneLok and Fingerprint function.
Grade Match measures and displays the existing grade over unknown ground. As a consequence it eliminates time consuming and error prone calculations
PlaneLok automatically locks on to an existing horizontal elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather.
The unique “Fingerprint” function only accepts the beam from the laser it is paired with. |

| Spectra HL760 Digital Readout Receiver - INCLUDED in GL422N Laser Package |
Highly versatile receiver for basic and advanced leveling and aligning applications
Works with GL422N in automatic Grade Match and PlaneLok applications |
 |
HL760 Laserometer Laser Receiver KEY FEATURES:
- LARGE 5-INCH RECEPTION HEIGHT
- Digital readout of elevation
- Exact distance from on-grade displayed
- Anti-strobe sensor to prevent false reading from jobsite strobe lights
- Withstands a drop of up to 10-foot
- Fingerprint function - detects only the laser beam of the paired transmitter
User Benefits:
- No need to go “on-grade” to measure
- Saves considerable time
- Reduces rework by allowing remote monitoring
- Increases reliability, accuracy and durability
|
GL422N when used with the HL760 DRO receiver, several advanced features can be utilized:
- Grade Match: Wireless communication between the HL760 receiver and the transmitters provide automatic Grade Match which connects different elevations and will actually calculate and display grade values between two points when using the GL412N and GL422N.
- PlaneLok: For applications that require maximum stability and accuracy is available on the horizontal Y-axis and in both vertical planes. PlaneLok automatically locks the beam on the DRO receiver and keeps it on-grade, reducing typical environmental factors that may induce an error.
PlaneLok for vertical alignments provides quick, accurate set-up and easy control.
- Also provides the ability to quickly set up a vertical plumb or slope reference.
