Sartorius AY303 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 313-1S. The Practum balances are an entirely new cutting edge design offering superior weighing technology over the AY303. The Practum 313-1S is a magnetic force restoration balance offering MUCH Better weighing performance over the AY303. We have NO remaining stock on the Sartorius AY303 and the manufacturer has discontinued production. All information displayed herein is for archival and support purposes only.
Beware of anyone trying to sell you the AY303 since the manufacturer warranty has ran out and there are no parts and accessories available from Sartorius. There are plenty of other alternative models available and if you need help give us a call. We just despise seeing some people selling AY303 to people as brand new when you are buying a scale with NO WARRANTY and NO AVAILABLE parts or accessories AVAILABLE FROM SARTORIUS. Don't be hoodwinked stay away from the AY303 and always buy a current production model.
For those people looking for a low cost scale that reads in milligrams be sure to see the EPB-103 , EPB-203 or EPB-303.
Sartorius M-Prove series are ideal balances
and scales for Educational, Industrial,
Laboratories, Research, Postal, Special
Applications and more. The Sartorius AY-303 milligram balance comes with a 300
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
Sartorius owned Acculab and shut down the brand in Dec of 2010. The AY303 by Sartorius is the exact same balance as the the Acculab Vicon 303 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
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
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
pounds, pounds:ounce, pennyweight,
troy ounces, grains, Newton, carats,
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
The scale also has lock-down capability, with glass ring, leveling bubble and adjustable
feet included on all milligram models.
As of 2013, Sartorius AY303 has been discontinued by Sartorius and there is no direct replacement in the same price range under the Sartorius brand. The closest to the AY303 would be the Sartorius Practum 313-1S listing for $1300 which is too expensive for most people when you can buy the AND FX-300i or A&D FZ-300i for a lot less money. If price is a major issue and you are willing to stay with a strain gauge loadcell like the AY303 used then be sure to review the EP303. All information displayed herein is for support purposes only.
If your budget is limited and you want an alternative to the AY-303 watch the video above that highlights the general features of the EBP203 milligram scale. We walk you step by step how the calibrate the scale. Learn how you can change the weigh mode from grams to pennyweight and how the scale will power up in the last weigh mode used. The features highlighted in this video are similar for the EPB103 and EP303 except the weighing capacity is 100 grams and 300 grams respectively. This is an affordable milligram scale ideal for the science classroom or hobbyist weighing small samples. Just like the AY303 the EPB milligram scales use a a strain gauge loadcell which allow the price to be so low compared the electromagnetic force restoration.

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 AY303 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

Round glass draft ring improves scales performance lessening air turbulence under platform. Available in this model and the AY-123 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.

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.
