Overview for the Topcon DL 502 32X Digital Auto Level

The  Topcon DL-502 Digital Auto Level with 32x magnification incorporates  cutting-edge technology to provide exceptional height, elevation and  distance accuracy. With a large internal memory, inverse staff reading,  wave and read technology, and pre-installed measurement programs, this  surveying and construction tool maximizes work efficiency and minimizes  error.

Stability and Speed

With a working range of up to 328 feet, the DL-502 has a height   accuracy of 1/32 inch per kilometer double-run and 3/8 inch at 33 feet   distance accuracy. This auto level has four measurement modes:   single-fine, repeat-fine, average and tracking. In addition, it is   equipped with a shock-resistant pendulum compensator with magnetic   damping system and allows you to take a single measurement in only 2.5   seconds.

Inverse Staff Reading

The Topcon DL-502 digital level automatically recognizes the barcode staff's direction and displays the result with a minus sign. Height of ceiling, overpass, bridge, road sign, tree branch, tunnel crown, and   other objects can be easily measured without a calculator.

Wave and Read Technology

The world's first wave and read technology provides an additional   survey style option that allows a rod operator to wave the staff back   and forth to read the correct height, instead of keeping it plumb. This simpler method is faster, easier, minimizes the fatigue and is just as accurate.

Internal Memory

Simply aim the barcode staff, adjust the focus, and press a single   key to measure height and distance. The results are immediately   displayed digitally on the backlit LCD and can be recorded in the 2,000 points internal memory.

Water Resistant

With an IPX4 rating, the DL 502 is protected against water splashes   from any direction. Even when the staff surface is partially shaded or   in dim lighting conditions, a single button triggers measurement and   this optical instrument instantly provides reliable results. It is also powered by a Li-ion-battery which is capable of supplying power for up to 16 hours.

This Topcon digital level package comes with a hard carrying case,   hex wrench, vinyl cover, battery, charger, power cable and 1-year   manufacturer's warranty.
