AND Weighing GP industrial balance with Super Hybrid Sensor (SHS) technology providing unsurpassed performance, speed and durability.  Improvements versus the HP predecessor with super fast response and robust durability using A&D’s patented SHS Technology, IP-65 rating, convenient automatic self-calibration with internal calibration mass and detached display (GP-KS models only).

For 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.

The 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. 

The 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.

A&D 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.

GLP/GMP/ISO Compliant
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 calibration data.

ID Number
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.

Density determination
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.

HI, 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.

Accumulation 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.

Internal Calibration
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 be required.

Display Auto Power ON & OFF
The display can be set to turn off automatically after 10 minutes of inactivity, which can be disabled if not desired.  Without pressing ON/OFF key, plug it in and the balance will turn itself ON, once the internal setting is set.

Data Memory
Standard Time & Date Function complies with GLP and Interval Weighing in the Data Memory function.  The data memory can be formatted for:

Time & Date
Standard Time & Date Function complies with GLP and Interval Weighing in the Data Memory function.

Auto Self Checking
Automatically checks itself when setting the Automatic Adjustment Environment.

Optional Underhook
Ideal for density determination and weighing magnetic substances

Interval Time Setting
Weighing intervals of 2, 5, 10, 30 seconds and 1, 2, 5, 10 minutes using the Data Memory Function.

Auto Re-Zero
Re-Zeros automatically after data output

Large Stainless Steel Weighing Pan
384mm x 344mm for GP12K/20K/32K/32KS/30K/30KS/40K/60K/60KS/61K/61KS
386mm x 346mm for GP100K/100KS/102K

Multiple Weighing Units & Programmable Unit
Standard (selectable) units of measure include (g, kg, lb, lb/oz, oz, troy oz, carat, pennyweight, momme, tola, tael, percentage, density 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.

SmartRange
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.

Optional AD-1682 Rechargeable Battery Unit
Now you don't have to worry about finding a power line for those remote office trailer labs when performing weighing applications for highway or construction sites.  The AD-1682 can power the GP-Series for typically up to 7 hours of operations when the Ni-MH batteries are fully charged.

All A&D's balances equipped with an RS-232c and can use the A&D WinCT balance communication software to interface your computer with your A&D balance.
