Spectra Precision - laser levels

---

  The GL612N Grade Laser provides single grade capability of 25% in addition to being fully self-leveled in vertical for building axis alignment or setting 90 degrees. Simple, robust and easy to use with a menu-driven interface that is replicated on the radio remote control makes the GL612N the first choice for any contractor requiring versatile grade capability. 

Features:

• Multiple Applications – the GL612N provides the ability to control level, alignment, single grade and set 90 degrees.
• Long Range – one person elevation and grade control with 800 m (2,600 ft) diameter range increases productivity
• Automatic self-leveling – provides fast, easy set-up for horizontal level, grade or vertical alignment
• Automatic Grade Matching – meaning the laser moves to the on-grade position on the receiver automatically by communicating wirelessly with the receiver and the grade is then calculated – this is generally used when a constant fall is desired, but the grade may not be known (renewing existing driveways or matching existing surfaces)
• Grade Range – large, fully compensated grade range from -25% to 25% – keeping the laser leveled no matter what grade you need reducing errors and improving productivity.
• Anti-Vibration Filter – a laser can be affected by high vibration or strong wind, especially when the laser is mounted on a tall tripod –both the GL612N and G622N have an anti-vibration filter that can be set according to the conditions allowing work to continue regardless of wind conditions or excessive vibrations.
• Temperature Compensation & PlaneLok– as temperature fluctuates throughout the working day, the internal components of a laser can expand and contract which can cause some additional error without the user noticing. This is can be resolved through the automatic temperature check that the laser performs where the internal software calibrates the laser to its optimal performance based on the temperature. Additionally, the PlaneLok function can be activated. This keeps the laser beam fixed to a receiver in a set a position eliminating any error that can be caused by fluctuating temperatures, keeping the laser accurate and error free.
• Rugged – the GL612N can withstand a 1m (3 ft) drop directly onto concrete or 1.5m (5 ft) pushover on a tripod, eliminating costly repairs.
• Mask Mode – the GL612N has a virtual masking function that allows the laser beam to be turned off in up to 3 sides, avoiding false reading from glass reflections or interfering with other lasers on the same jobsite.

 Spectra Precision® GL622N Grade Laser — Easy-To-Use, Full Featured Automatic Grade Lasers. The GL622N Dual Grade Laser is rugged, automatic self-levelling laser with grade capability from -25% to + 25% and can be used for a wide variety of grade, excavating and alignment applications by general and specialty contractors. 

Features: 

• Multiple Applications – the Spectra Precision GL622N provides the ability to control level, alignment, dual grade and set 90 degrees. The GL622IR is not used for vertical alignment or 90-degree layout.
• Long Range – one person elevation and grade control with 800 m (2,600 ft) diameter range increases productivity
• Automatic self-levelling – provides fast, easy set-up for horizontal level, grade or vertical alignment (vertical on GL622N only)
• Automatic Grade Matching – meaning the laser moves to the on-grade position on the receiver automatically by communicating wirelessly with the receiver and the grade is then calculated – this is generally used when a constant fall is desired, but the grade may not be known (renewing existing driveways or matching existing surfaces)

Additionally, the PlaneLok function can be activated. This keeps the laser beam fixed to a receiver in a set a position eliminating any error that can be caused by fluctuating temperatures, keeping the laser accurate and error free.
• Automatic Axis Alignment – A critical factor when working with grade is alignment to the grade hub. If an alignment is off, error can be introduced and exaggerated. The GL622N has an Automatic Axis Alignment function, allowing the user to set-up simply and quickly, maintaining accuracy and eliminating costly errors.
• Rugged – the GL622N and GL622IR can withstand a 1m (3 feet) drop directly onto concrete or 1.5m (5 feet) pushover on tripod, eliminating costly repairs.
• Mask Mode – the lasers have a virtual masking function that allows the laser beam to be turned off in up to 3 sides, avoiding false reading from glass reflections or interfering with other lasers on the same jobsite.

 The Topcon RL-H5A Self-Leveling Rotary Laser is accurate 1/16 in. at 100 ft., a range of up to 2,600 ft. and leveling within 5. Its slope matching feature makes it an excellent tool for excavating.
