The NA700 Series are the engineering-grade automatic levels: nitrogen-filled telescopes and IP57 immersion protection, from the general-purpose NA720 and NA724 through to the NA730 plus at 0.7 mm per kilometre. Per-kilometre double-levelling accuracy runs 2.5, 2.0, 1.5, 1.2, and 0.7 mm across the NA720, NA724, NA728, NA730, and NA730 plus. The telescopes reach 20x to 30x magnification, and the compensating level is set to under 0.3 seconds on the 728 and above. They are built for precision control, long-baseline height transfer, and staff-based grade checking, and they survive being dropped and rained on.
