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 display.

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.

The AY303 uses strain gauge weighing technology which allows you to buy a milligram scale for a low cost, but you do give up performance and accuracy so consider this before you buy. Strain gauge sensors drift and although the display might increment in one milligram graduations they are not accurate to a milligram. Sartorius states the linearity (also known as accuracy) as ± 0.004 grams. To get away from a strain gauge load cell we recommend the more costly electro-magnetic force weigh cell found in alternative milligram balances like the A&D FX-300i, Scientech ZSP350 or Sartorius AZ313. Before you buy anything please watch our YouTube video - Strain gauge loadcell vs electromagnetic force restoration.

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.

Does the new Sartorius AY-303 look like the Acculab VIC-303? Well it is basically the same scale molded in a different color plastic housing and a new color keypad overlay and of course a higher price.

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
