One-secondprecision
NET1200 employs original absolute encoders with
new algorithms. One-arc-second angle accuracy is
equal to 0.5mm (0.02in.) at 100m (330ft.) and 1mm
(0.04in.) at 200m (650ft.). By minimizing the angle
measurement error, total accuracy of 3-D coordinates
has been remarkably improved.
Idealtelescope
The telescope of NET1200 provides an image
unrivalled in both brightness and sharpness. By re-
designing the optics and mechanics, the telescope
has been made smaller allowing operators wearing
hard hats to perform sighting with greater comfort and
ease.
Ultra-highperformanceEDMbroadens
theboundariesof3-Dmeasurement
Sokkia has developed a new EDM with state-of-the-art
digital signal processing and sophisticated optical
technologies. It outperforms its predecessors in all
fields such as range, speed and precision.
Higher precision and longer range with
reflective sheet targets
The distance accuracy of the NET1200 is ±(0.6 +
2ppm x D)mm which is equal to ±0.8mm (0.03in.) at
100m (330ft.) and ±1mm (0.04in.) at 200m (650ft.).
By using a 50x50mm target, the measuring range has
been doubled to 200m (650ft.), which enables 3-D
measurement of larger objects. Thanks to this new
EDM, the need to constantly relocate the instrument
point is reduced, and therefore total precision of 3-D
measurement is improved.
Reflectorless measurement capability
NET1200 incorporates the reflectorless measurement
function to measure objects without using any target.
So now even points where a target cannot be
manually affixed can still be measured. The visible red
laser beam enhances the scope of the NET1200
further. Being ultra-narrow it can measure with
pinpoint accuracy those points whose complex or
convoluted situation had previously hampered
accurate measurement. The measuring range is 40m
(130ft.) with white surfaces (90% reflective) and
accuracy is exceptionally high at ±(1 + 2ppm x D)mm
- equal to 1.08mm (0.04in.) at 40m (130ft.).
Long range measurement with prisms
With the Sokkia's AP surveying prism, NET1200
measures up to 2,000m (6,500ft.) with ±(2 + 2ppm x
D)mm precision. CPS12 high precision prism provides
±(1 + 2ppm x D)mm accuracy up to 350m (1,140ft.).
High-speed measurement
With the reflective sheet or reflectorless, distance is
measured every 0.9 seconds (initial 4.8s).
Laser-pointerand
targetilluminationfunctionsforeasyaiming
These two new functions greatly facilitate operation in
the field.
Laser-pointer function
The EDM beam is also used as a convenient laser
pointer for pinpointing the measuring point. This
function also boosts the efficiency of setting-out tasks
under considerably low light conditions such as inside
a factory building.
Target illumination
A white LED is built into the upper part of the
telescope section. This LED illuminates the direction
in which the telescope is aimed allowing the operator
to easily sight a
target at long range
even in poor light.
You can select "on"
or "blinking", and
the brightness can
be adjusted to suit
the environmental
conditions.

Weather-proofcompactbody
Thanks to its superior IP66 structure, the NET1200
can be relied upon even in rain, on dusty worksites,
and in other harsh working environments. And
moreover, what with the new compact body weighing
only a mere 5.5kg (12.1 lb.), the unit is much more
portable.
Long-lifedetachablebattery
One Li-Ion detachable battery supplies power for
approx. 6 hours of continuous operation. Two
batteries, which provide enough power for one full day
of work, are equipped as standard. Recharging time is
under 2 hours per battery with the quick charger -
included as a standard accessory.
All-in-onecarryingcase
The standard carrying case can
hold the SDR4000/4E/4C
control terminal in addition to
all the standard accessories
such as batteries, chargers,
operator's manual, and more.
Operationviacontrolterminalfor
maximumprecision
If the control terminal SDR4000 is connected to
NET1200, all operations, with the exception of target
sighting, can be performed with the SDR4000. Once
the object has been sighted the operator does not
have to touch the NET1200 at all so giving the
greatest possible precision.
