Rapid, Stable, and Durable Compensator
The compensator of AT-B Series incorporates four suspension wires made of super-high-tensile metal that features minimal thermal
expansion coefficient, providing unmatched
durability and accuracy. Finely tuned magnetic
damping system quickly levels and stabilizes
the line of sight despite the fine vibrations
present when working near heavy equipment
or busy roadways.

Optical Micrometer

Standard Package

• AT-B Level

• Hex wrench
• Adjusting pins
• Vinyl cover

• Lens cap
• User manual
• Hard carrying case

All-Weather Dependability
With the IPX6 rating, the instrument is
protected against powerful water jets from all
directions, meaning the AT-B Series withstands
a sudden shower or torrential rainfall. The
advanced protection design also deters
clouding or condensation inside the telescope.

Horizontal Circle for Angle Measurement
Horizontal angles can be directly
read in 1° or 1gon units. Free rotation feature allows you to read any angle from zero. The circle is covered for protection against dirt and scratch. The readout window is located below the eyepiece for quick reading.

20cm (7.9 in.) - Ultra-Short Minimum Focus
The AT-B Series can focus on objects at 20cm (7.9 in.) in front of the telescope. This feature dramatically facilitates the works in confined spaces.
