The Sartorius AY123 has been discontinued and no longer in production as of January 2013. The Sartorius AY line was phased-out and replaced with the new Practum 213-1S. The Practum balances are an entirely new cutting edge design offering superior weighing technology over the AY123. The Practum 213-1S is a magnetic force restoration balance offering MUCH Better weighing performance over the AY123. We have no remaining stock on the AY123 and all information displayed herein is for archival and support purposes only.

Sartorius AY123 [120g x 0.001g] operates AC Adapter ONLY, has a 4 inch diameter weighing pan with round glass draft ring, and the 100 gram calibration mass is included. Built in Arvada, Colorado and backed with a 1-year parts and labor limited factory warranty.

The Sartorius AY123 is a low cost milligram scale since it's weigh cell is built using strain gauge technology. The strain gauge can give you good weighing results for weighing static loads, but can drift much more due to temperature variations caused by excitation energy used with a load cell strain gauge weigh sensor. You'll get better performance, linearity and repeatability with an electromagnetic weigh sensor like those found in the A&D FX-120i or Scientech ZSP150 but this weigh sensor design cost more money. If you don't understand then watch this video HERE demonstrating a magnetic force restoration balance verses strain gauge scale. If you're on a tight budget and your weighing results aren't for a super critical application then the Sartorius AY-123 might be your best choice.

Gun & ammo pros can weighing bullets or arrowhead in increments of 0.02 grain intervals. If you are a ammo reloader checkout this performance testing article at accurateshooter.com before buying the AY123. If you want an idea how much faster you can increase your reloading speed using the Sartoius AY123 verses the GD503 be sure to review www.snipershide.com.

Gun and ammo reloaders really need to watch the video above that one of our customers put online. See the Sartorius GD503 in action and where professional shooters all over the world are learning to forget those low cost strain gauge scales that don’t work (see this video to see the difference). Watch the reloading of bullets using the Sartorius GD503, Omega Powder Trickler and the RCBS Chargemaster. A kernel of Hogdgon H4350 powder weighs between 0.025 – 0.030 grains and the Sartorius GD503 increments in 0.005gn. If you are tired of all the headaches using digital scales in the past it is time for you to buy a real balance that can weigh correctly. Give us a call at 978-521-7095 and we will configure the GD503 so the balance works out of the box in grains. If you are buying the AY123 for reloading we really think you should buy the Sartorius GD503.
If you are a ammo reloader checkout this performance testing at accurateshooter.com on the GD503. If you want an idea how much faster you can increase your reloading speed be sure to review www.snipershide.com
Sartorius M-Prove series are ideal balances and scales for Educational, Industrial, Laboratories, Research, Postal, Special Applications and more. The Sartorius AY-123 milligram balance comes with a 120 g capacity and 0.001 g readability. Whether weighing multiple samples with totaled results, formulating a color, counting, percent weighing, specific gravity or under pan weighing, Sartorius has the answer in M-Prove. All models feature a flip-down protective cover for safe transportation and stackability, integrated cal-weights, stainless-steel pan and large back-lit display. Sartorius owned Acculab and shut down the brand in Dec of 2010. The AY123 by Sartorius is the exact same balance as the the Acculab Vicon 123 except they changed the color of the plastic from gray to white, changed the overlay keypad and changed the display slightly and, of course, raised the price. Superior Engineering for Better Performance and Durability The ultra-fast microprocessor gives enhanced weighing performance and exceptional stability. All M-Prove series sensors are robotically manufactured for measurement uniformity and greater durability, and each sensor is computer optimized for maximum performance, providing higher output and unmatched repeatability. These M-Prove milligram balances have incomparable overload protection for years of service in all weighing applications. The display on each scale is a white back-lit display for easy viewing in all ambient weighing conditions. Unique State of the Art Features All M-Prove series milligram scales are stackable for convenient, safe storage that saves valuable counter space. They have an integrated weight chamber, which simplifies calibration and the reversible weighing pan allows greater flexibility in weighing samples. In all there are 13 models of scales (enhanced by two milligram units). The rugged housing is made of ABS plastic with maximum overload protection, and the protective flip-down and removable plastic cover is great for protection of the scale in shipping and stackable storage. The balance comes with integrated external calibration weights on models with capacity of 710 grams and below. Applications include: Counting, Percent Weighing, Totaling, Display Hold, Specific Gravity. The 14 Mass Unit Conversion units of measure include grams, ounces, pounds, pounds:ounce, pennyweight, troy ounces, grains, Newton, carats, Taels HK/Taiwan/Singapore/China, user defined. This M-Prove weighing balance comes with such accessories as optional RS-232 or USB interface kit (field installable),and an AC adapter (or optional 9 volt battery operation excluding milligram models). The external "one button" calibration has 3 weight options. The scale also has lock-down capability, with glass ring, leveling bubble and adjustable feet included on all milligram models
Round glass draft ring improves scales performance lessening air turbulence under platform. Available in this model and the AY-303 only.
Above are the two versions of the Sartorius M-Prove AY Series. The front scale represents models AY-123 and AY-303. Model AY-212 also has the round pan but does not come with the draft ring. All the other M-Prove AY Series balances come with the square pan as appears on the rear scale.
Integrated external calibration weights for easy storage.	View of the RS-232 and USB cable interface cables and input.
All of the Sartorius M-Prove AY Series scales are stackable for ease of storage.
Excellent LCD backlit display with quality buttons. Shown above is the sprint bubble indicator (AY123 and AY303 only models with sprint bubble).
Watch video how to configure your Sartorius AY digital scale. We show you how to change the primary weigh mode to a different weigh unit other than the factory default of grams only. The user manual doesn't tell you how to change the primary weigh mode but our video does. Below in the table are the codes needed to change the primary weigh unit.

Watch video how to calibrate you Sartorius AY digital scale. Calibration weights are included on the AY123, AY303, AY212, AY412, AY612, AY511, and AY711. Calibration weights ARE NOT INCLUDED with the AY1501, AY3101, AY5101, AY4000, AY6000, AY10000.
Keep those cordless phones, smart phones and other electronic devices that emit radio frequencies since it really can effect the performance of your digital scale.
