410g with 1 milligram readability, standard built-in RS-232 interface and internal calibration at a touch of the button.  Animal weighing for maximum accuracy, the entire GX Series can be programmed to average readings over a set period of time -- ideal for weighing lab animals or for work in unstable environments.  A&D is made in Japan and is our best selling line of precision balances with facilities in Milpitas, California and Stone Mountain, Georgia.  Scroll fully down this web page so you can review all the specification and even download the instruction manual.

Many people call us looking for the absolute best value Precision Weighing Balances can offer in a milligram balance and the answer again and again is the Sartorius GC2502.  These customers are not looking for the lowest priced milligram balance, but instead how can they get the most balance for their money relative to the specifications each balance offers.  We believe the value is unmatchable in the GC2502 since you get lightening fast weighing results, 500 grams weighing capacity with 1 milligram readability, high quality 3 door removable draftsheild, included 200 gram external calibration mass and all topped off with a 3 year limited manufacturer warranty .  You can read more about the Sartorius GC2502 HERE.

Another great value you should review is the Mettler Toledo JL1503-C/A03 featuring an ALL GLASS draft shield and weighing 302 grams weighing capacity and 1 milligram resolution.  The Mettler-Toledo JL1503-C/A03 does not have the internal motorized calibration like the GX400, but Mettler supplies the 200 gram calibration mass for external calibration at no additional cost.  See more about the Mettler HERE.

If price is absolutely the #1 factor in you purchasing a 200 gram balance with 1mg readability designed with internal motorized calibration then we would recommend you take a look at the ACCULAB ATL-423-I Balance (420g x 1mg) here.

A&D GX-400 Milligram Scale

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.
