We just slashed our prices on the A&D GR-Series for several good reasons. First, the internet consumer demands the lowest possible price and we clearly display our best price online for hassle free shopping. Second, people love the GR Analytical Series they're telling colleagues resulting in explosive growth of our company and the A&D line. Selling more allows Precision Weighing Balances to lower the cost to the end users. Third, we like converting users of other brand balances and making people think- is that made in Switzerland balance really worth the difference in price?? 

A&D has perfected the analytical balance with the introduction of the GR-Series. Innovative design will continue to serve your weighing requirements for years to come. Flexible to meet almost any of your high precision weighing needs with the added versatility of built-in applications including counting & percent weighing.

The A&D GR Series is your "Total Weighing Solution" offering internal motorized calibration, RS-232 interface and balance data communication software all packaged together for one low price. Other manufacturer's charge you $100's more for either their balance communication software or a third party software but not with the A&D GR Series. Purchase the GR Series and you can have a paperless documented trail using WinCT data acquisition software and your PC.

If your application, such as a cleanroom, limits your ability to a PC you can still achieve ISO/GLP compliant output available via the RS-232(standard with all GR-Series) using the optional AD8121B printer. Now you can achieve today's stringent traceable requirements.

The GR-Series features the easy access door system. The tall draft shield can accommodate even tall flasks up to 8.64 inches in height. A built-in motorized calibration weight for optimum accuracy is possible at any time with a press of a button.

High performance and quality is shown with a 5 year manufacturer warranty. The A&D GR Series is made in Japan and A&D Weighing has two facilities in the USA located in Georgia and California if your balance ever needed repair.

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 Company, Ltd. has grown from developing digital-to-analog converters for companies such as Nippon Telegraph & Telephone, to becoming a world class producer of advanced measuring equipment for medicine, science and industry. A&D established itself as a multinational corporation, with offices in the United States, Great Britain, Germany, Australia, Korea, Taiwan and Russia, and as a world leader in measurement equipment. The company's competitive edge is the direct result of its ability to leverage strong engineering and manufacturing capabilities, while incorporating highly accurate analog and digital technologies into broad product lines focused to provide customers with the greatest value.

There is lot's more to read about the A&D GR Series here.

If you like the touch screen design we also offer the Sartorius Secura 124-1S, Quintix 124-1S and Practum 124-1S . The Sartorius Secura 124-1S allows you to enable SQmin and additional safety weighing features like the ability to program the minimum weight value so when you attempt to weigh samples below a set threshold the weight reading is displayed on screen in red. Built-in level verification, Password Protection, and memory tracking is also available. Secura is one of the worlds most technologically advance weighing instrument we offer.

We understand purchasing a laboratory analytical 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.

The GR-120 is a nice analytical balance and has been around for over a decade. Some people comment the GR120 is outdated and lacks a true USB interface, touchscreen display, the GR120 side doors can not be easily removed for cleaning. If these issues matter to you then be sure to review the Sartorius Quintix 124-1S that offers the lastest in weighing technology at an amazing affordable price.

Precision Weighing Balances is an Authorized A&D Weighing Dealer.  Beware of other vendors trying to sell you A&D balances since you may be short changing yourself with a balance that has no warranty.  Buying from an Authorized Dealer insures your warranty begins from the date of our invoice.

Need more accuracy? Do you need a 5 decimal place gram balance? The Sartorius Secura and Quintix semi microbalances are amazing. In the YouTube video above you will see the Sartorius Secura225D-1S semi microbalance [0-120g x 0.01mg] [120-220g x 0.1mg]. We highlight the intuitive operation using the SmartTouch user interface that is so easy to use you'll probably never need to reference the user manual. We also demonstrate the ergonomic draftshield and show how easy it is to dismantle the balance for easy cleaning.

Also you'll get a close up view of the new "collection container". The collection container is designed to keep the spill from entering the lab balance that could cause potential damage to the balance. Sartorius' revolutionary "collection container" features a rimmed design to keep the spill from entering if you happen to spill any liquid or granular samples while weighing.

If the Secura225D-1S is more balance than you need for your weighing application then be sure to see the Secura 125-1S, Sartorius Quintix125D-1S or Sartorius Quintix65-1S. Sartorius is our #1 selling laboratory weighing balances since they are the leaders in building high quality weighing instruments.
