Nikon AC-2S Automatic Level
From the Manufacturer
High-performance automatic levels featuring airtight, dry-nitrogen-filled optics. Waterproof and fog proof, these instruments provide high accuracy in humid tunnels, unforgiving terrain, and inclement weather. Key features for AC-2S automatic level are that it is compact and lightweight (1.25 kilograms/2.8 pounds). The built-in compensator automatically levels the line of sight over a wide compensation range of ±16 inches with a setting accuracy of ±0.5 inch. The powerful 24x telescope has a 30mm objective lens for clear, bright images in an erect and unreversed orientation.
The minimum focusing distance of 0.75 meters/2.46 feet lets you work even in confined places. Standard deviation for a 1-km double-run level is just ±2.0 mm. The horizontal tangent knobs have an unlimited range and can be operated with either hand. A friction brake enables quick, easy setting. The detachable eyepiece lens can be replaced with an optional diagonal eyepiece prism. Includes a specially designed base plate for mounting on either flat- or domed-head tripods. The water-resistant body construction allows use in light rain or dusty conditions. The AC-2S model is identical to the AC-2, except for the stadia line.
