Design, features, quality and price.  We feel no other precision balance manufacturer can match when you compare the GF-30K against the competitors models.  This is a true high precision balance that meets IP-65 ratings for water and dust proof.  Larger 10.6" x 8.3" weigh pan and 31,000 grams weighing capacity with readability to 0.1 gram.  Yes - this means the balance increments in 0.1 gram interval all the way over the complete 31000 gram range.

Fast, new Super Hybrid Sensor (SHS) gives you the ultimate in response speed - Just 1.5 Seconds!  SHS combines the best of magnetic force restoration and single point parallelogram load cell technologies.  If the time ever comes where the SHS needs repair, you just replace one of three parts - there is no need to replace the whole weigh sensor as is the case with higher priced, slower competitive models.  This new, innovative sensor is a core technology certain to dominate in the 21st century.  Made in Japan by A&D Weighing, a global manufacturer of high precision instrumentation, with facilities in California and Georgia to back and support the 60 month manufacturer warranty.

Standard built-in RS-232 interface allows you to easily connect the balance to a PC with included WinCT software included with all A&D laboratory balances.  You can import the data into your PC software, such as Windows based Word/Excel software.  This balance data communication software is included as standard equipment unlike other manufacturer's that charge $100's for their software.

Need to use the balance in a area without a computer??  No problem A&D the standard RS-232 interface can be tied into the optional 8121B data printer to meet your GLP/GMP requirements.

GF-K Series offers external calibration only and requires the purchase of the optional calibration masses if you desire to calibrate the balance.  Animal weighing for maximum accuracy, the entire GX-K / GF-K Series can be programmed to average readings over a set period of time -- ideal for weighing lab animals or for work in unstable environments. 

Multiple weighing modes available by simply pressing the "Mode" key and scroll through the desired weigh unit whether it is grams, ounce, pounds & more.

Precision Weighing Balances is an authorized A&D Dealer so you can buy in confidence that all units are brand new and come with the full 5 year manufacturer limited warranty.  We always recommend you purchase from an authorized dealer since otherwise you risk buying a "gray market" unit imported from a foreign country and may not have any warranty at all.

Never heard of A&D?  A&D is currently the world's third largest manufacturer of laboratory and industrial balances with 20% of the world market share.  Established in 1977, A&D Weighing has offices in the United States, Great Britain, Germany, Australia, Korea, Taiwan and Russia, and as a world leader in measurement equipment. 

We understand purchasing a high capacity precision balance is a major capital expense and if you have any questions give us a call and we can discuss your weighing application and get you the most affordable balance for your weighing needs.

A&D Weighing GF-30K Electronic Scale

The picture above shows you just how large the A&D Weighing's GX-K and GF-K Series actually is.  That's the GF-12K on the left and the A&D HL-400 with a 12 oz Michelob Light Beer on the scale.
A&D GX-K and GF-K Precision Balances can most easily be described as an extension of our current GX & GF Toploaders duplicating the many versatile operation features, but providing higher capacities (up to 31kg) and larger pan size (10.6" x 8.3").  The GX-K (like current GX) have internal calibration while the GF-K (like current GF) have external calibration only. If the GX-K and GF-K Series 10.6" x 8.3" isn't large enough then we offer A&D top of the line industrial balance - the GP Series with its behemoth 15.1" x 13.5" weighing pan. GX-K/GF-K industrial balances are built with the Super Hybrid Sensor® (SHS) technology to improve response speed, accuracy and minimize maintenance costs.  These digital industrial scale is available in capacities from 2 kg to 30 kg and max 0.01 g readability. SHS combines the best of magnetic force restoration and single point parallelogram load cell technologies.  Its unique design provides the fastest response speed in its class - just 1.5 seconds!  And if the time ever comes when the SHS needs repair, you just replace one of three parts - there is no need to replace the whole sensor as is the case with higher priced, slower competitive models. All models come standard with RS232 interface and WinCT balance data communication software.  Multiple weighing modes available by simply pressing the "Mode" key and scroll through the desired weigh unit whether it is grams, ounce, pounds & more. For users on a budget that require high resolution over a limited range, A&D introduces SmartRange on the 8K2 & 32K models.  SmartRange allows the operator to select a movable fine range throughout the entire weighing range of the balance. Rugged die cast aluminum alloy/stainless steel construction, makes the GX-K / GF-K Series the strongest and longest lived industrial balance in its class. Choose the GX-K Series and you'll have motor-driven internal calibration at just push a button!  You'll also have 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.
