Product Details

WinCT Communication SoftwareThis precision balance can be connected to a computer using the RS232 port and the included WinCT software. This software can be used with Windows based computers to transmit data to and from your Apollo precision balance.

Fast & Accurate With Magnetic Force RestorationThis balance is equipped with magnetic force restoration, or electro-magnetic force, to provide super fast, accurate and repeatable measurements.

Programmable Auto On & Auto OffYou can program this precision balance to automatically turn on when the AC is plugged in and to turn off after a few minutes of inactivity.

Dynamic Weighing FeatureThis precision balance has a really cool dynamic weighing feature that will let you get accurate weights of unstable items, this is especially great for weighing animals!

Bi-Directional USB & RS232 PortThe A&D GF-303A has an USB & RS232 port built right in. This is important if you're wanting to send your weight readings and other data to an external source like a computer or printer.

Overload ProtectionThis protection system prevents damage to your scale from accidental overload. The GF-303A has a visual indicator that will let you know when you're about to cause damage to your scale from excessive overload.

Reverse Backlit LCDThis scale has a fancy backlit display to help you see your weight readings, even in dim lighting.

Impact Shock Detection (ISD)This feature allows you to visually and audibly receive alerts that indicate the magnitude of impact shocks. You can also view a log that stores the date, time and level of shock for easy review.


Flow Rate Display (FRD)A common technique for determining flow rate is to use a stopwatch or your PC to keep time. This can cause disparities as those tools are not always in perfect sync with the precision balance or scale you are using. This can cause spikes in your readout even if the flow rate remains constant. The GF-303A features a flow rate calculation function which provides a feedback mechanism that compensates for the spikes in your readings. Giving you a more accurate and precise flow rate for your dosing or filling applications. Using the scales comparative function, you can monitor the flow rate data to make sure it does not exceed its specified limits.

Checkweighing With Visual HI/OK/LO IndicatorsTo make sure you get your weights just right, this precision bench scale has a comparative feature that will let you set your target weight. Once your target weight is set, the GF-303A will let you know when you're over, under or just right by displaying a "HI", "OK", or "LO" symbol on the screen.


Electronically Controlled Load (ECL)The GF-303A has the ability to perform internal diagnostic checks using a repeatability test without the need for any external weight. This checks the conversion stability between analog to digital before it applies the controlled load inside of the balance. This greatly decreases the time other traditional repeatability test would take while also providing more accuracy.

Checkweighing FeatureTo make sure you get your weights just right, this precision scale has a checkweighing feature that will let you set your target weight. Once your target weight is set, the GF-303A will let you know when you're over, under or just right.

Percent WeighingThis feature will let you compare the weights of your samples against a predetermined reference weight. This can be helpful in weight checking, compounding, formulating and more.

Does This Thing Count?You bet it does! All you need to do is weigh a sample amount of pieces, so the GF303A can know how much each piece weighs, then start counting. You'll be finished in no time.

ACAI™ (Automatic Counting Accuracy Improvement)This function will improve the accuracy of the unit weight by re-calculating the unit weight with each additional amount of pieces you put on the scale. This is gonna make counting your parts and pieces super accurate and super easy.

Removable Stainless Steel PlatformThe GF 303A has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily and keeps its shine without rusting or tarnishing.

Easy CalibrationThe GF-303A is factory calibrated and ready to use. This industrial scale will rarely need calibrating, but if you use it ALL of the time, or you want to be sure you're getting the most accurate weight readings, you might want to calibrate it from time to time. You'll just need to pick up a 200 gram calibration weight, (not included) to get the job done.

Weighing HookSometimes the thing you need to weigh just won't fit on the scale's platform. Now that's a problem for most scales, but not the A&D GF 303A. This scale has a weighing hook built right into the bottom. This hook works by pulling on the weighing platform when an item is hanging from it, just like if you were to put an item on top of the platform. Just uncover the hook, and hang your item from it to weigh.

Tare FeatureThe tare button on the front of this digital scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the items you're adding. This sure is useful when you want to use an expansion scoop to weigh your things, or if you want to get separate weights of multiple items.

Liquid Level IndicatorThis very handy feature will help you quickly and easily get your scale nice and level. A level scale is important for getting the most accurate weight readings.

5 YEAR MANUFACTURER'S WARRANTY!This compact balance is covered with a 5 year warranty from A&D Weighing against defects in material and workmanship.
