Weigh construction materials up to 31kg with readability to 0.1 grams for geotechnical weighing applications. Determination of particle size distribution of aggregate by sieve analysis of bituminous paving materials requires that you accurately weigh the material of each sieve and the GP30K reads to 0.1 grams. Plus if you purchase the optional GP20 underhook you'll be able to perform the weighing in water method where you immerse the specimen in water while suspended under the balance.
Test procedures like the determination of the bulk specific gravity of asphalt (bituminous) concrete cores carried out in accordance with AASHTO T166-88I call out a precision balance that conforming to the requirements of AASHTO M231 (Accuracy within 0.2 % of
known weights at 5 points
through the scale range)
A&D GP Series offers the fastest weighing technology and didn't stop here.
Now all GP balances 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. There is a lot more to learn
about this spectacular product and you must scroll down to read all the features.
AND claims their GP Series High Precision 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.
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 industrial 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'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 offices in the United States, Great Britain, Germany, Australia, Korea, Taiwan and Russia, and as a world leader in measurement equipment.
High performance and quality is shown with a 5 year manufacturer warranty.
The A&D GP balance is made in Japan and A&D Weighing has two facilities
in the USA located in Georgia and California if your balance ever needed repair.

users on a budget that require high resolution over a limited range,
A&D introduces SmartRange on the GP-32K, GP-32KS &
GP-102K models. SmartRange allows the operator to select
a movable fine range throughout the entire weighing range of the balance.
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.

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.
