GP20K precision industrial balance 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 GP20K to state Department of Transportation Offices throughout America to meet many of your AASHTO testing applications.

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 shipping scales 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.

Connect your AND Washdown Bench Scale to your computer using WinCT Software.  Connect the RS232 interface to either your computer's serial port, or else using a USB adapter.  Using this 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 data.
