The Leica NA524 is a 24× automatic level with 2.0mm/km accuracy. It is Leica's entry-level construction automatic level, suited for site grading, benchmarks, and floor surveys where high precision is not required.
Leica NA524 Automatic Level — Complete Specs, Manual & Guide
Category: Automatic Level | Brand: Leica | Model: NA524
The Leica NA524 is a dependable construction automatic level known for its robust build quality, smooth focussing, and long service life. At 24× magnification and ±2.0mm/km accuracy, it is well-suited for site grading, utility benchmarks, and everyday construction leveling. The magnetic damped compensator handles setup on slightly uneven ground, and the sealed housing resists dust and rain for outdoor site use.

Frequently Asked Questions — Leica NA524
What is the accuracy of the Leica NA524?
The NA524 achieves ±2.0mm standard deviation per kilometer of double-run leveling. This makes it suitable for construction site grading, foundation benchmarks, and pipe laying grade checks. For higher-accuracy leveling (±0.3–1.0mm/km), a digital level such as the Leica Sprinter or Sprinter 150M is required.
What is the magnification of the Leica NA524?
The NA524 has a 24× magnification telescope with a 31mm objective aperture. This provides adequate image clarity at typical construction distances of 20–80m. At maximum range, lighting conditions significantly affect rod reading accuracy.
What is the difference between the Leica NA524 and NA528?
The NA528 offers 28× magnification and improved ±1.5mm/km accuracy compared to the NA524's 24× and ±2.0mm/km. The NA528 is preferred for precision construction leveling and floor flatness surveys; the NA524 is the standard workhorse for everyday site leveling.
How far can you shoot with the Leica NA524?
The NA524 is practical for sight distances up to approximately 60–80m in good lighting. Beyond 80m, rod reading errors increase significantly. For longer sights, consider using a digital level with electronic bar-code rod reading.
Is the Leica NA524 compatible with Leica grade rods?
Yes. The NA524 reads any standard metric or imperial leveling rod. It does not read barcode rods electronically — that requires a digital level. Compatible Leica rods include the BROD12 aluminum series and GS12 fiberglass rods.
