Product Description

From the Manufacturer

High-performance automatic level 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 AS-2C Automatic Levee: Waterproof- The airtight, gas-filled (dry nitrogen gas) design of the telescope is perfect for wet or humid environments. Nikon-Inches unique automatic compensator employs a wire-suspended pendulum and an air damper to prevent magnetic interference. And the wide compensation range (±12-Inch for AS-2C) makes it quick and easy to set up. Rugged construction provides excellent resistance to shocks. Highly accurate 1km double run leveling- AS-2C ±0.8mm without micrometer, ±0.4mm w/micrometer AS-2C features horizontal circle. Direct readings are graduated to 10-Inches and can be estimated to 1-Inch. The model AS-2C employs a 34x high-magnification, high-resolution telescope to assure sharp images even in poor light. Optional high- and low-power eyepiece lenses- AS-2C High-power 43x, Low-power 22x. Improved minimum focusing distance, down to 1m/3.28 Feet., for better performance in tight spots. Endless horizontal fine drive ensures smooth, precise pointing and angular measurement. To ensure rapid rotation, a new friction break does away with the need for clamps. Standard optical sight lets you find your target with precision and ease. A mirror with a pentaprism lets you view the circular bubble as an erect image while setting up and sighting. Attaches to both flat- and spherical-head tripods.
