Trimble has introduced the new Spectra Precision DR400 DigiRod
combination productivity tool. It is designed to eliminate the need for
grade rods when checking grades with a rotating laser. The combination
of a laser receiver with digital readout, laser distance meter and
built-in tilt sensor provides the information required to take rod-less,
accurate grade readings, even at tilt angles up to 30 degrees.

Using the DigiRod, various grade rods can be emulated including direct elevation rods,
cut/fill rods and indirect reading rods. Users can select measurement
units in meters, decimal feet or fractional inches with the press of a
button. This eliminates the need to carry, transport and maintain
multiple grade rod types. Elevation measurements can be taken up to 6
meters and the tilt sensor ensures accuracy by automatically
correcting to actual vertical distance. The user simply places the laser
distance meter spot on the location a grade check is required, picks up
the rotating laser beam anywhere on the reception window, and the
distance from ground to the rotating beam is measured and displayed.
Errors due to rod math and out of plumb grade rods are virtually
eliminated. The rod-less grade checking system also allows for safe
trench and excavation grade checking as workers do not have to climb
down in the trench or lean over unstable trench edges to obtain
elevation readings. Screeded concrete can also be checked without
leaving marks on the finished surface.

Elevation measurements can be taken up to 6
meters.


 

Based upon the popular HL700 Laserometer, the DigiRod functions as a
laser receiver and will work with any rotational red beam laser. The
receiver has an extra-long 127 mm vertical reception range that
does not require centering on-grade to obtain a reading. The large LCD
screen gives a bright, clear digital readout of elevation that
eliminates confusing calculations. An anti-strobe sensor stops
construction strobe lights from setting off the receiver. Multiple
accuracy setting allows adaptation to meet jobsite requirements.

As a stand-alone laser distance meter, the DigiRod is designed to
provide contractors with a one-person distance measuring and estimating
tool to measure remote and difficult-to-reach places such as high
overheads, factory interiors or over water. It can measure up to 50
meters and has an accuracy of plus or minus 2.0 mm. A
continuous measure mode is useful for staking out various distances and a
minimum/maximum function accurately measures diagonals and right angles
to surfaces. In addition, the DR400 is dust and waterproof and backed
by a five-year warranty.

The versatility, portability and functionality of the DR400 DigiRod can
add value beyond the traditional construction markets and can include
applications in surveying.
