AND Weighing GP20K is a necessary piece of equipment for the research, design and quality control of materials of most construction/civil engineering projects. Determination of particle size distribution of aggregate by sieve analysis for bituminous paving materials requires a quality accurate balance and the GP20K offers 21000g weighing capacity with readability to 0.1 grams.
To ensure the aggregate used performs as intended for highway construction, several tests are performed to determine the physical characteristics of the material. The large stainless steel weighing pan measures 15.1" x 13.5" can accommodate most sieves for particle analysis. Dust and water resistant IP65 ratings of the AND Weighing GP20K ensures your precision weighing instrument will survive the sometimes dusty work environment. Numerous AASHTO, ASTM and public works materials testing procedure call out weighing specifications similar to the GP Series. The optional GP20 underhook allows for air & water weighing for determination of density.
Save money with A&D industrial bench scale's full digital calibration. An expensive calibration weight is not required with AND's digital internal
calibration. When the balance detects ambient temperature changes, it self-calibrates, giving you precision readings you can trust every time.
You may also calibrate the scale on-demand simply by pushing a button. GP Series civil engineering lab balances incorporate A&D's enhanced weighing sensor,
the Double Leveraged Super Hybrid Sensor (SHS). Building on the basic SHS features of speed and stabilization, AND's enhanced SHS technology brings
the most accurate weighing results to industrial balances in the 12 kilogram to 101 kilogram
capacities class (see all the different models HERE).
Connect your AND wash down bench scale to your computer using WinCT Software.
Connect the RS232 interface to either your computer's serial port, or purchase the optional USB to RS-232 adapter. Using WinCT balance communication software, automatically log your bench scale's
readings on your computer.
A&D claims their GP Series washdown bench scales are the world's most user-friendly industrial balances. Resistant to dust, water, and moisture, AND GP
Bench Scales are IP65 compliant. Choose between the swing arm indicator or the detachable display platform scale models.
A&D's optional AD-8121B Dot Matrix Printer offers GLP, GMP, and ISO compliance
by outputting the date, time, balance ID number, serial number, and calibration
Never heard of A&D? A&D is currently the world's third largest manufacturer of laboratory and industrial balances with 20% of the world market share. Established in 1977, A&D Weighing has grown from developing digital-to-analog converters for companies such as Nippon Telegraph & Telephone, to becoming a world class producer of advanced measuring equipment for medicine, science and industry. A&D established itself as a multinational corporation, with offices in the United States, Great Britain, Germany, Australia, Korea, Taiwan and Russia, and as a world leader in measurement equipment. The company's competitive edge is the direct result of its ability to leverage strong engineering and manufacturing capabilities, while incorporating highly accurate analog and digital technologies into broad product lines focused to provide customers with the greatest value.

GP features a rugged die cast aluminum alloy/stainless steel construction,
making it the strongest and longest lived industrial balance in its
class. A&D dominates the high capacity, high precision market
especially in the asphalt and aggregate marketplace because they're
built to survive. From California to Florida we have been supplying
the ever popular HP-20K to state Department of Transportation Offices
throughout America and now we can offer the GP-Series to meet many
of your AASHTO testing applications.
GP Series offers the ability to set the function parameters to inhibit
the automatic calibration feature. In the automatic calibration
mode, calibration may be initiated when ambient temperatures change.
This may hamper your measurement process when warm aggregate is being
weighed. Other balances on the market sometimes perform auto
calibration if the aggregate is warm enough to trigger the internal
sensors, just when you want to use the balance.
GP Series offers the fastest weighing technology and didn't stop here.
Now all GP-Series come standard with internal
calibration and the RS-232 interface.
The internal calibration makes calibrating your GP Balance easy when
you relocate or bump your balance. Just push a button!
The GP will even perform Automatic Self-Calibration, calibrating the
balance when it detects changes in the ambient temperature.
The GP is Rugged
The GP series is constructed of a die-cast aluminum body and stainless
steel weighing pan, assuring safe operation in demanding applications.
Low maintenance costs and longer product life make the GP Series the
premiere high capacity toploading balance on the market today.
The GP Balance is protected from dust and spills up to IP-65/NEMA4
Allows GLP or LIMS balance management by outputting the Balance ID
number and data used to calibrate the balance. The data can
be output to A&D's AD-8121 printer or a PC, indicating date, time, Balance ID number, serial number and
The balance ID number can be set. It is used to identify the
balance when GLP is used. The ID number is memorized and maintained
once it is fixed, even if the AC adapter is removed.
GP is equipped with a density determination mode, which is accessible
after changing the internal parameter settings. Once the object's
weight in the air, in the liquid and the liquid density are input,
the solid density will be calculated.
OK, LO Indicator
When the MODE key is pressed, the display is refreshed and the indicator
changes from HI to HI.
The letters (HI, for example), can be enlarged. This feature
allows the user to set the HI and LO parameters and quickly determine
if subsequent weighments are within the set tolerances.
of weighing results
GP offers a built in accumulator and transaction counter. Simply
place the item to be weighed on the platform and push the print button,
each weighment will be added and the accumulated value displayed.
Pushing the mode button will show the number of accumulated weights
stored in the transaction counter.
GP balances have a motorized built in calibration
weight. The internal calibration weight is equivalent to
a 50kg calibration mass. Of course, the GP can be calibrated
with optional external weights where calibration tractability may

mode, and a user definable unit of measure). In addition, the
GP has an Animal Weighing program that freezes the display after a
predetermined time allotment.
For more accurate weighing, SmartRange function is provided for the GP32K or GP32-KS (6.1kg x 0.1g/31kg x 1g) and GP-102K
(61kg x 1g/101kg x 10g). The precision range has a higher resolution
and the standard one is normal resolution. Pressing the RE-ZERO
key allows weighing in the precision range, regardless to the tare
value. SmartRange function
enables you to weigh or add samples in the precision range without
removing the container and/or those objects that have been placed
on the pan.
