The GX4100 (4100g x 0.01g) self-calibrates automatically when the balance detects ambient temperature changes. A&D is made in Japan with facilities in Milpitas, California and Stone Mountain, Georgia.  Scroll fully down this web page so you can learn all the specifications and even download the instruction manual so you can learn all about this state of the art weighing machine.

For those people looking for the best possible 0.01 gram balance for the money maybe you should consider the Sartorius GP5202.  We feel the GP5202 precision toploader from Sartorius is the best value Precision Weighing Balances has to offer and we have them in stock for immediate delivery.  You can increase your weighing capacity by 1000 grams without sacrificing the resolution for hundreds of dollars less.  Why pay more for less?

GP5202 toploading balance offers a maximum weighing capacity of 5200 grams and readability to 0.01 gram intervals.  This precision balance features a backlit LCD display, HUGE 7.4" x 8.0" weighing platform [A&D GX4000 is only 6.5" x 6.5"], RS232 interface, parts counting mode, and external calibration all for an unbelievably low price.  A&D's GX series balances feature internal calibration, while the GP5202 from Sartorius offers external calibration only.  To many people internal calibration is a really nice feature and if you believe this then maybe the GX-4000 is the best choice for your weighing application.  We prefer external calibration because it is more affordable, and external calibration is truly the only way to calibrate a balance to insure accuracy.  Click here to learn additional benefits of external calibration verses motorized internal calibration.

Another similar model you should review is the Sartorius GW6202 precision balance.  This balance is very similar to the GP5202 except it has a higher weighing capacity of 6200 grams plus the GW6202 offers motorized internal calibration.

Another unbelievable balance you need to review is the Mettler-Toledo JB4002-GA-F featuring 4100 grams maximum weighing capacity and increments in 0.01 gram divisions.  This Mettler Balance offers FACT (Fully Automatic Calibration Technology), which automatically initiates the internal adjustment of Mettler balance whenever temperature changes risk affecting the accuracy of your weighing results.

If price is absolutely the #1 factor in you purchasing a 4000 gram balance with 0.01g readability designed with internal motorized calibration then we would recommend you take a look at the ACCULAB ATL-4202-I Balance (4200g x 0.01g) here.

A&D GX4000 precision balance

A&D is a recognize leader in precision weighing instruments and has developed significant technical breakthroughs in design and manufacturing.  In 1985, for the first time in the balance industry history, A&D incorporated digital calibration and multi-point linearity adjustment in their analytical balance series.  By exploiting chip technology, A&D was the first to bring surface-mount technology to the miniaturized PC boards to the weighing industry .  They brought extremely competitive counting, bench, and compact scales to the market by deploying aluminum to manufacture the most cost effective, reliable load cells.  Using innovative designs and progressive manufacturing techniques, A&D brought cost effective, RFI-immune digital weight indicators to the market place.  Today, A&D is proud to continue this tradition of innovation.  Introducing the Super Hybrid Sensor.  This new, innovative sensor is a core technology certain to dominate in the 21st century.

Features Fast, new Super Hybrid Sensor (SHS) gives you the ultimate in response speed - Just ONE Second! Internal Calibration and Internal Calibration Mass makes calibrating your GX Balance easy when you relocate or bump your balance. Just push a button! Automatic Self-Calibration calibrates the balance when it detects changes in the ambient temperature Large, bright Vacuum Fluorescent Display - see the display even in the dark Percentage, Counting Functions & Comparator functions ACAI Counting Function for highly accurate counting There are so many more features to reinforce that the GX-Series is one of the finest precision weighing balances that you should click here to learn more All A&D GX-Series come standard with built-in RS-232c and A&D WinCT balance communication software on CD-Rom to interface your balance with your computer.
