Design, features, quality and price. Attributes we feel no other precision balance manufacturer can match when you compare the GF30K against the competitors models. This is a true high precision balance that meets IP65 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 Milpitas, California and Norcross, 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.

Many people call us looking for the absolute best value Precision Weighing Balances can offer in a high capacity precision balance and the answer again and again is the Mettler-Toledo SB32001-GA which offers a larger weighing platform (13.74" x 9.13"), external calibration only, but the Mettler SB32001-GA offers 32,100g x 0.1g and this Mettler balance is Legal for Trade.  Finally the unbelievable low price is a major buying factor that makes the Mettler SB32001-GA our #1 seller.

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.
