The world’s first “Wave-and-Read” technology provides an additional survey style option that allows a rod operator to wave the staff forward and back, instead of keeping the staff plumb. This simpler method is faster, easier, minimizes the fatigue and is just as accurate.
Internal memory and easy data transfer
The DL-500 stores the data for up to 2,000 measurements. MAGNET Office Tools software provides visual tools for post processing, adjustment, and customized reporting.
Single button operation
After focusing on the staff, just press one button. The DL-500 reads height and distance, and stores data. Auto levels require you to read the graduations on the staff with your own eye, but digital technology eliminates misreading and reduces eye fatigue.
Versatile Performance
Maximum reliability field-proven compensator
Incorporating a field-proven pendulum compensator with magnetic damping system, the DL-500 provides the stability you need when working on busy roads or bridges subject to vibration.
Measures ceiling height Inverse staff reading
The DL-500 can read the RAB-code staff in the inverted position. This dramatically facilitates height measurement of ceilings, tree branches, road signs, bridges, tunnel crowns, and other structures.
“Wave-and-Read” technology
The DL-500 tracks the RAB-code staff when waved forward and back, and automatically reads the correct height. The reading is at the minimum when the staff stands vertically, automatically finding the least value of staff readings.
Practical measurement programs
No need for calculators
On-board programs support various measurement routines such as elevation, height difference, ceiling height, as well as cut/fill and stakeout in horizontal distance.
