Electronic Digital Level DL-101C / 102C

DL-101C

TOPCON's DL-101C / 102C takes accuracy and ease of operation to a higher level with its Advanced Image Processing Technology. The outstanding features make the DL-101C / 102C ideal for high precision applications including the performance of 1st and 2nd order leveling and deformation monitoring.

	Faster Automatic Measurement When used with TOPCON's unique patterned staff, height and distance can be automatically determined digitally by the DL-101C / 102C. Since it's a fully automatic electronic measurement, there is no need to make an optical reading! You just sight the staff, focus, and press the measurement button. It's that simple! The results appear in the clearly visible display window after about three seconds.
	Highly Accurate Measurement The fully automatic measuring ability and digital display of the DL-101C / 102C excludes any reading errors, writing mistakes in the field book, and other possible human-made errors. Consequently, the electronic measurement data is always more precise and more reliable as compared to the conventional visual measurement.
	Increased Productivity up to 50% With TOPCON's DL-101C / 102C, all leveling work can be carried out automatically, quickly and more economically as compared to the performance of conventional optomechanical levels. This effortless and error-free measurement makes it possible to have up to a 50% increase in productivity.
	5m staff Levelling staffs of a variety of materials and length are avaiable with the special Topcon pattern to allow Digital Measurements with DL-101C / 102C.
	Data Output Function Standard RS-232C port provides an instant communications link with a data collector or direct output to a personal computer.

Electronic Digital Level DL-103 series

DL-103

Approved by Geographical Survey Institute of Japan: DL-103R/103A class 2 electronic levels

	High-accuracy surveying performed by only pressing "MEAS" key after pattern staff collimation. A digital level for civil engineering execution.
	Excellent resistance to environmental phenomena, including vibration, non-uniformity in lights and shades and heat haze. Waterproof structure of IPX 6.
	No need to read the pattern staff scale. Uniform surveying assured without individual differences by surveyors as in the past.
	Distance to pattern staff can also be measured.
	Relative height difference or elevation from a control position can be displayed in the Height Diifference mode.
	Four R6 alkaline batteries (AA size) can continuously power the level for 20 hours.
	DL-103R (With RS-232C output)
	DL-103A (With auto focusing function)
