The TOPCON GPT-2000 Series non-prism
Total Stations make use of state of the art laser pulse technology to
achieve non-prism measurement capability. Distances can be measured without
the use of EDM reflecting glass prisms and long distance measurement can
be achieved when using a reflector.
TOPCON adds this non-prism function to the best selling
and rugged GTS-220 Series. As a result, the World's first "Non-Prism
- All Weather" Total Stations join the Topcon product line. Long
range non-prism function and tough durability against the environment
makes the TOPCON GPT-2000 Series the ideal and most powerful instrument
for a wide variety of surveying applications, from volumetric survey
and mining surveys to geodetic control and topographic surveying.
FEATURES
Long Range
TOPCON's unique pulse laser technology has made it possible for GPT-2003/2005
to measure a long range of 150m [100m for GPT-2006/2009] without prism
and 7,000m [4,000m for GPT-2006/2009] with a single reflector.
The GPT-2000 Series provides the best measurement performance under
any field condition.
As a result you will achieve increased productivity and efficiency with
many survey tasks.
High Speed Non-Prism Measurement
Due to the specialties of pulse laser technology, measurement is virtually
instantaneous (0.3 sec in tracking mode and 1.2 sec in fine mode.) Fine
focusing on each measurement point is not required. As a Class 1 invisible
laser is used, the operation is completely safe for operator, rod person
and passersby.
Simple Operation
The GPT-2000 series is based on the toughest and best selling Total
Station GTS-220 Series. These total stations have powerful yet extremely
easy to use surveying and stake-out software. The measurement mode is
also software controlled so depending upon the field application you
can change from non-prism to prism measurement simply by one key press.
Large Internal Memory
The GPT-2000 Series has the internal memory to store up to 8,000 points
for data collection, or up to 16,000 points for layout work.
Dual-Axis Compensator
A dual-axis compensator is included in the GPT-2003/2005/2006 models.
This dual-axis tilt sensor automatically corrects the vertical and horizontal
angle compensation for mis-leveling error, ensuring accurate and reliable
angle readings.
TOUGHEST DURABILITY AGAINST
THE ENVIRONMENT- WATERPROOF/DUSTPROOF
IP66!! WORLD'S
FIRST IP66 FOR NON-PRISM
INSTRUMENTS
The GPT-2000 Series will stand up to any
wet weather or dusty jobsite condition that can occur in the field,
giving the benefit of no down time due to inclement weather. The waterproof/dustproof
protection (IP66) of the GPT-2000 Series assures durable performance
in the field under all conditions as the world's first "All Weather
Pulse Total Stations".
* Degree of protection against water
for TOPCON's GPT-2000 Series is based on the standard IEC60529, defined
as "Water projected in powerful jets" against enclosure from
any direction shall have no harmful effects. And also GPT-2000 complies
with "Dust-tight" of the IEC60529 standard as to degree of
protection against solid foreign objects, defined as "No ingress
of dust".
NON-PRISM FUNCTION
Non-Prism Plane Offset Program
With TOPCON'S "Plane Offset Program"
you can measure to the edge or corners of Buildings and Structures with
precision!!
The technology used by all manufacturers
of "reflectorless" Non-Prism Total Stations allows for discrepancies
in distance measurement under certain application conditions, especially
when measuring to an inside corner of a building, or when measuring
to the edge of any wall or plane. All prismless Total Stations have
expanding beam widths that widen over distance. In particular, you will
potentially see distance errors when measuring to an edge, or corner,
where part of the measuring beam may extend to the rear, or in the case
of an inside corner, forward, of the target, as illustrated in the drawing
below. This measuring error can occur regardless of the beam's width.
However, you can work worry-free with the
TOPCON GPT-2000 Series. TOPCON's exclusive, "Plane Offset Program"
is standard on all GPT products, and solves this industry wide problem.
Just measure three (3) random points on a wall or plane to establish
a known plane. Then sight the unknown point on the plane and the GPT
calculates coordinates and distance values of the desired point. With
the "TOPCON Plane Offset Program", you can measure to the
edge or to the corner of buildings and structures quite precisely.
