If you need an NTEP balance approved balance then review the GF3000N or any of the FXi-N NTEP digital scale (FX-1200iN, FX-2000iN or FX-3000iN).

Another balance to review before you make your final purchasing decision if you want motorized internal calibration is the Sartorius GW6202, but the GW6202 in not legal for trade.

GW6202 digital precision balance offers a maximum weighing capacity of 6200 grams and readability to 0.01 gram intervals. This precision balance features a back-lit LCD display, HUGE 7.1" x 7.1" weighing platform [A&D GF3000 is only 6.5" x 6.5"], RS232 interface, parts counting mode, and internal calibration all for an unbelievably low price.

If price is absolutely the #1 factor in you purchasing a 3100 gram balance with 0.01g readability designed with a force restoration magnetic motor then we would recommend you take a look at the AND FX-3000i precision balance.

We understand purchasing a quality precision balance is a major capital expense and if you have any questions give us a call and one of our weighing experts can discuss your weighing application and get you the most affordable balance for your weighing needs. Precision Weighing Balances has been selling lab balances online since 1995 and we know balances so well we've been hired by some of the most prestigious law firms in America as an expert witness. Sadly, most of the catalog companies and vendors online have never even turned on a balance and can't answer any questions about how the balance functions.

A&D GF3000 Toploader Balance

The GF-Series offers all the spectacular features of the GX-Series except the internal motorized calibration feature has been removed.  Therefore, the GF3000 precision lab balance has the same display, features,  ip-65 rating, SHS technology except there is no internal calibration mass.  ISO 9000 procedures favor the calibration of balances with an external certified calibration mass.  A balance with internal motorized calibration weight is a nice feature, but costly.  Most balances with the internal calibration feature also offer external calibration.  External calibration is vital since it is much more convenient to send out the external calibration mass for recalibration/certification verses the costly fee of having the internal calibration mass removed from the balance and sent out for re-calibration. In addition, if you own several of the same balances just one external traceable calibration is needed for ISO compliance. Precision Weighing Balances always recommends that you purchase the calibration mass with any balance you select.  This allows you to calibrate the unit yourself without requiring the services of an outside calibration firm.  Best of all calibration couldn't be simpler.  Connect the AC adapter and warm up the balance with nothing on the weighing pan.  Then simply turn "ON" the balance, allow the balance to go through the power-up routine and then press and hold the "CAL" until "CALout" is displayed.  The display walks you through the cal procedure in less than 1 minute.  The entire cal is controlled by the user-friendly keypad.  The days of opening the balance and tweaking those potentiometers and trim resistors to calibrate a scale are gone with the advent of the digital circuit and EPROM technology first implemented by A&D Engineer's.

All A&D GF-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.
