Highlights

• Precise leveling
• Rapid, easy set-up
• Reliable automatic compensator
• Precise collimation

The automatic level from Sokkia offers the best of our famed leveling technology in a more compact easy-to-use design. Tougher smaller, and more tightly sealed against humidity and dust - for superior performance whatever the conditions. Better yet, this latest model is just a quick and easy to set-up, simple to sight, and immune to vibration, shock, and other environmental conditions.
Fully resistant to rain and accidental dousings, it won't fog even with sudden temperature changes - leaving you free to concentrate on the work. This model meets JIS grade 4 specification for waterproofing. (This complies with international Electrotechnical Commission Standard, Class IPX4).

Precise leveling

the reticle can be fitted with the optional parallel plate micrometer for precise measurement in increments of 0.1mm (estimation 0.01mm).

Rapid, easy set-up

Using a spherical-head tripod, setting up the level is fast and easy even on angled, uneven surfaces. Set the level onto the tripod head, centre the circular bubble, and away you go. It also fits flat-head tripods.

Reliable automatic compensator

Four suspension wires and magnetic damping action ensure stability, even under rapidly changing atmospheric condition, vibration, and shock. Precise damping even comes with "hangups" in the compensator

Precise collimation

this model incorporates an endless horizontal motion drive with two knobs for fast and easy aiming, operable by right or left hand. Simply turn the instrument, then use the fine motion to aim the level at the target precisely. A two-speed focusing knob switches between coarse, and fine focusing for even faster operation. The optics are designed to be bright and easy to use.
