Offering you the best of Sokkia's renowned leveling technology, the C300, C310, 320 and C330 automatic levels are compact, solid, fast and very user-friendly. For a start, setting up the levels can be done fast and quickly and sighing is just as simple.
Moreover, the C3 series automatic levels guarantee superior performance regardless of weather conditions. Apart from being immune to vibration, shock and other environmental conditions, the C3 models are fully resistant to rain and accidental dousing. Even in sudden weather changes you won't be disturbed by fogging of the instrument - you're left free to concentrate on the job.
Thanks to this solid, water and shock proof, design, the C3 levels are just as well suited for outdoor use as for indoor use.
All C3 models meet 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).
Stadia
The stadia lines on the reticle make calculating distance easy: simply multiply the distance on the rod between the top and bottom stadia by 100.
Easy To Adjust
With the provided tools, adjusting the reticle can be done easily by simply adjusting gone screw. Adjustments to the circular level vial can be made by adjusting two screws.
Precise Collimation
All C3 models incorporate an endless horizontal motion drive with two knobs for fast and easy aiming, operable with either the left or the right hand. After turning the level in the right direction, it can be aimed at the target more precisely by using the fine motion feature.
