Introducing the newest line of multi-functional balances from A&D Weighing. GX-A offers precision and protection when weighing sensitive materials in high-risk environments or weighing with automated devices.

Enabled by the Smart Super Hybrid Sensor (SHS) technology, GX-A includes three new innovative features from A&D:

  • Impact Shock Detection (ISD)

    • Impact-Alert – displays the magnitude of impact shocks to the weight sensor at four levels, with audible notification for higher levels of impact which should be avoided

    • Shock-log that records time, date, shock level and operator ID, making quality control easier to pinpoint. 

    • Real-time feedback mechanism prevents equipment damage, and allows managers to modify in-line or manual processes alike. An important feature when transverse and vertical environment forces are unpredictable.

  • Electronically Controlled Load (ECL)      

    • Allows the user to perform a diagnostic check and repeatability test without the need of an external test weight

    • At the touch of a button and in under two minutes, users gain a daily precision verification test with Dia-Check.

    • Determine a standard deviation and calculate the minimum sample weight with Quick-MinS, and ensure operations are USP41 compliant with Min-S-Alert.

    • Ensures critical measurements are compliant with industry standards such as USP 41 and 1251.

  • Flow Rate Display (FRD).

    • Avoid irregularity that can arise in traditional filling and dosing applications, the Apollo series features an FRD function.

    • The FR-Calc feature calculates and displays the mass or volume flow rates to close the “time-clock disparity” found with traditional PC methods.

    • FR-comparator, which allows monitoring of flow rate data to ensure it is kept within designated limits

    • Tare value can be saved in non-volatile memory so that the remaining amount of the material in the container can be displayed again, even if power is disrupted during loss-in-weighing measurement.

This new combination of features enhances accuracy and precision, while reducing the amount of rework required - lowering costs. The GX-A provides a weighing solution which truly supports lab and production operators in the quest for greater efficiency.


    •  Auto precision assessment (APA) and minimum weight calculation using electronically controlled load (ECL)

    •  Cushioning under the weighing pan to mitigate impact shocks

    •  Protection against vertical and transverse static overloading

    •  Flow rate comparator that indicates whether the flow rate is within the designated limits

    •  Fast stabilization of approx. 1 second (approx. 1.5 seconds with the GX/F-1603A and GX/F-10002A)

    •  One touch calibration using internal weight

    •  Automatic self calibration to maintain accuracy under temperature changes

    •  Timed calibration function

    •  Large, front-mounted spirit level with LED illumination

    •  Easy-to-adjust leveling feet with thumbwheels

    •  Clearly visible, reverse backlit LCD display

    •  Multiple weighing units: g, oz, lb, lb-oz, ozt, ct, mom, dwt, grain, specific gravity, and a user-programmable unit for conversion applications

    •  User access control (UAC) function that password-protects the balance at two  levels

    •  GLP/GMP/GCP/ISO compliant output to meet documentation requirements

    •  Gross/Net/Tare output

    • 5 Year Warranty


      • Counting mode with the Automatic Counting Accuracy Improvement (ACAI) function

      •  Data memory function: save weighing results, calibration results and unit masses for the counting mode in the device itself

      •  Tare memory function that saves the tare value in non-volatile memory

      •  Alert function to ensure that the measured quantity is not smaller than the set minimum weight

      •  Percent mode function for target weighing or checking sample variation

      •  Statistical calculation function (SCF) to facilitate the analysis of measurements

      •  Key lock function to make the balance operable only by sending commands from an external device

      •  Clock and calendar function

      •  Five-level comparator function with buzzer

      •  Animal weighing (average & hold) function for weighing moving objects

      • Universal Flexi Coms (UFC) function to edit serial data output/printout format

      •  Auto power ON and OFF functions

      •  Underhook for weighing a magnetic material and/or measuring density

      •  Density determination function (optional density determination kit available for the 0.001 g models)

      •  Security slot in the rear for an anti-theft lock
