One touch levelling,
Sure, safe & simple
The first builders digital levels
the DL-103 series is the latest in the line of Topcon digital levels,
positioned to cause a revolution in the use of electronic levels for construction
site levelling tasks. The DL-103 series is specifically designed to be
easy to operate and quick and accurate in taking staff readings for all
construction site levelling tasks normally carried out using optical levelling
instruments.
New:
Auto Focus
The recently introduced DL-103AF is the first digital level on the market
with built-in auto focus. Levelling cannot get any easier: just sight
the staff and press the button! The measured value is displayed in two
seconds.
No staff reading errors
The DL-103 series uses advanced Topcon digital imaging technology to read
a specially patterned staff. This eliminates the need for visual interpretation
of the staff reading and therefore removes a major source of error in
construction sight levelling work. DL-103 series provides reliability
and consistency in staff readings.
Robust
and water protected
The DL-103 series is of a robust construction, has a functional
design and is protected against water penetration so that it can be
used safely and reliably on a construction site even in wet conditions.
Water protection class is to the international standard IPX6 (DL-103)
and IPX4 (DL-103AF), which is better than many optical levels that are
available on the market.
Long battery life
DL-103 series uses four AA size batteries and has a low power consumption
that allows 20 hours continuous operation. The remaining power level
is indicated in the display so there is always a warning about a low
power. Battery life is preserved by the Auto Cut Off function that turns
the instrument off if not used for 30 minutes.
Levelling staves
Topcon offers a full range of low cost levelling staves with the
special Topcon bar pattern for use with the DL-103 series. Staves of
a variety of materials, aluminium, wood, fiberglass and a variety of
lengths, 3m, 4m or 5m are available.
Operating functions:
- Height difference calculation
- Distance calculation
On site applications:
DL-103 series is particularly suitable for one shot readings where
optical observation errors can go unchecked:
- Transfer of levels from one known height to another position.
- Setting out of levels for concrete structures and slabs
- Setting out of road levels
- Setting out of drainage pipe and gully levels
- Survey of existing levels and level grids
- As build checking of concrete structures, inspection covers, and
drainage pipeline levels
Levelling runs and loops, local control networks and establishing temporary
benchmarks.
