Leica NA724 Automatic Optical Level: Unyielding Precision for Demanding Sites

The Leica NA724 Automatic Optical Level is engineered to defy the toughest construction site conditions, delivering reliable and highly precise measurements day in and day out. With a 24x magnification and robust construction, it's an ideal choice for surveyors, civil engineers, and construction professionals who require consistent accuracy and minimal downtime, even amidst heavy rain, dust, and vibrations from machinery.

This instrument is a testament to over a century of Leica Geosystems' expertise in optics and precision engineering, providing users with a tool that works as hard as they do.

Features

• Exceptional Durability and Robustness:
  • IP57 Rating: Fully protected against dust ingress and resistant to immersion in water (up to 1 meter for 30 minutes). This means it can be used confidently in adverse weather conditions or even after being dropped into shallow water, minimizing downtime.
  • Shock-Resistant: Built to withstand impacts and vibrations common on construction sites. Leica rigorously tests these levels to withstand impacts with accelerations up to 700G (ISO 9022-33-5 standard), ensuring accuracy is maintained even after accidental drops.
  • Gas-Filled Telescope: The telescope is nitrogen-filled to prevent internal fogging of the lens, ensuring a clear view in varying temperature and humidity conditions.
• High Precision Optics:
  • 24x Magnification: Provides clear, crisp, and bright images, enabling precise targeting and accurate readings over practical working distances.
  • "Best in Class" Optics: Offers outstanding contrast and a sharp, upright image, reducing eye strain and allowing for comfortable and accurate readings even in low light conditions (e.g., early morning or twilight).
  • Short Minimum Focusing Distance: Capable of focusing down to 0.5 meters (1.64 feet), allowing for work in very confined spaces.
• Reliable Automatic Compensator:
  • Features a highly stable and reliable air-damped compensator with a setting accuracy of less than 0.5 arc-seconds and a working range of ±15′. This compensator automatically levels the line of sight, ensuring highly accurate measurements even when the instrument is slightly off-level.
  • The stability of the compensator minimizes the need for frequent checks or recalibrations in the workshop, reducing cost of ownership and maximizing uptime.
• User-Friendly Operation:
  • Simple Setup: Quick and easy to set up for daily tasks.
  • Circular Bubble and Horizontal Circle: Positioned conveniently next to the telescope for easy reading and approximate targeting.
  • Double-Sided Endless Drives: Provide smooth and precise horizontal movement, allowing for quick and accurate targeting without play.
  • Selectable Angle Measurement: The horizontal circle can be read in either 360 degrees or 400 gon, depending on user preference or project requirements.
• Accuracy:
  • Typical deviation for a 1 km double leveling run: 2.0 mm.
  • Accuracy for a single measurement at 30 m target distance: 1.2 mm.

Applications

The Leica NA724 is a versatile and reliable tool for a wide array of leveling tasks across construction and surveying:

• General Construction: Setting out levels for foundations, floors, ceilings, and walls.
• Building Site Preparation: Establishing grades for excavation and earthworks.
• Landscaping: Determining levels for patios, driveways, garden features, and drainage.
• Road and Pathway Construction: Checking and setting gradients.
• Drainage and Pipe Laying: Ensuring correct fall and alignment for utility installations.
• Formwork and Shuttering: Setting accurate heights for concrete pours.
• Industrial and Machinery Leveling: For high-precision alignment tasks in industrial settings.
• Height Transfers: Transferring vertical elevations across a site or between points.
