Product Details

Compact Super Hybrid Sensor (C-SHS) TechnologyThe A&D Compact SHS combines magnetic force restoration and double lever system to bring you fast stabilization and high resolution. This increases productivity for all weighing work-flows.

3.3" High Draft Shield When you're weighing with milligram balances like this AND FX120i, even the tiniest breeze can interfere with weight readings. That's why the FX-120i comes complete with a 3.3 inch tall draft shield to keep out those pesky drafts.

Programmable Auto Off Feature If you've ever have your scale turn off on you in the middle of important measurements, you'll realize what a blessing this feature is. You can program the FX-i to turn off automatically after about 10 minutes of inactivity, or to stay on until you turn it off yourself.

Dynamic Weighing Feature This 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!

Checkweighing Feature To 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 FX-120i will let you know when you're over, under or just right.

Percent Weighing This 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 FX120i 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.

Bright Vacuum Fluorescent Display (VFD) This digital scale has a fancy VFD display with bright blue digits so your weight readings will be nice and clear. Benefits of the VFD compared to LCD are a wider range of viewing angles, brighter digits, better contrast and easy viewing from greater distances.

RS-232 Serial Port The A&D FX120i has an RS232 port built right in. This is important if you want to send your weight readings and other data to an external source like a computer or printer.

Removable Stainless Steel Platform The FX 120i 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 Calibration To make sure you keep getting the best weight readings from your scale, it helps to calibrate it from time to time. Calibrating this digital scale is easy, you just need to pick up a 100 gram calibration weight (not included) to get the job done.

Weighing Hook Sometimes 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 FX 120i. This scale has a weighing hook built right into the bottom. This hook works by pulling on the weighing platform when you hang an item 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 Feature The 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 Indicator This 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.

Question
What calibration weight do I need?
Asked by: mdvga on September 10, 2020 7:10 AM
Answers
We recommend the ASTM Class 2 or Class 3 100 Gram Calibration weight. The Class 3 has a tolerance equal to the resolution of the FX-120i, and the Class 2 has a tolerance of 0.0005 grams.

I wish I had just bought this scale from the start rather than messing with cheaper scales to claimed to be good. Very Fast response time. Very accurate and consistent. Very little to no drift noticed thus far. Good for weighing, trickling up to weight, counting, etc. I use for powdered meds, dry chemicals, smokeless gunpowder, etc. Time and money wasted on other scales before this. Love it. Trust me, you won't regret it.

I have been reloading since 1983, I keep up with the ever-increasing advancements in reloading equipment that will help create more accurate ammunition, a lot of that new equipment has saved a lot of time/labor. Powder scales are no exception to those advancements. YouTube is a great source to see/find these great new products, the reviews/videos on the AND FX-120i convinced me to purchase one, I also ordered the AND Auto Trickler, with these two units that are designed to work together, powder weight accuracy will be unsurpassed...! I am currently waiting on the AND Auto Trickler that was ordered in April, should be here by late summer/early fall.... can't wait...!!

I bought this because I was looking for a better reloading scale. I like the RCBS Chargemaster I have (and it meets its published specs, no complaints) , but I’m doing long range work and want repeatability, and a bit more accuracy. The scale was easy to setup, and it works perfectly. I now know that a grain of H4350 weighs about 2 mg LOL. It will eventually get paired with an Autotrickler v3.0, but for now, I’m throwing from the Chargemaster then trickling up.

Not only did the scale exceed expectations for accuracy. It was simple to set up and pick the proper programs for my use. It showed, as I expected, that my current scale had WAY too much variance and wavering in its function. The icing on the cake was your service was way above average and the price was the lowest I could find anyplace that actually had the scales in stock.

After seeing and reading reviews on this scale, I decided to try it out. I was reloading with beam scales and cheaper digital scales that only went out to 10ths. I would always get frustrated when I would put a colonel or two or three or more and there would be no change on the scale and I wanted to take this out of the equation. So I decided to spend the money and get a lab scale that would measure out to 100ths. Looking at the A&D and Satorios scales, the Satorios is more money and claims to be more accurate. The A&D has a + or - of .02 and that is good enough for me. If you put 1 colonel of powder on the scale it will read it (.04grains H1000 ). It is very sensitive to wind and cold drafts even with the shields on, so you have to be careful where you set up the scale. A plus with the scale over the satorios is that in the future you ever want to add on a auto throw and auto trickler it is set up with the ports for it. Old Will Knott Scales had the best price and there support has also been good through out the process.

Purchased this scale to replace an aging and no longer consistent Ohaus load cell scale I have been using for loading precision long range rifle ammunition.

After a long and informative phone discussion with Elyce from Old Will Knott Scales I decided to upgrade to the "Magnetic Force Restoration" scale from the "Load cell" type.

this scale is very precise and consistent to 0.02 grain when weighing and later re-weighing various test weights from 2.68gr to 220.04gr and does not wander from zero once warmed up

Great scale and also great customer service from Elyce

I purchased this scale as an upgrade to my RCBS ChargeMaster for reloading (wanted more than 0.1 grain precision). Stumbled upon Old Will Knott. They had the best price, and ordering was easy. Shipping was fast! I received the product quickly (2 days) in pristine condition.

This is truly an amazing scale. It is fast and accurate! Build quality is excellent, and it performs exactly like you'd expect for the price. The abilities of the scale are quite remarkable. It can even calculate standard deviations from multiple weighings. The scale was able to pick up the difference with the addition, then subtraction of one (yes one) kernel of H1000.

If you haven't seen the AutoTrickler and AutoThrower add-ons for this scale from Adam MacDonald - GET IT NOW! The combo of this scale with his trickler and thrower is simply unbelievable! Four throws: 8s, 7s, 11s, 9s - All within 0.02 grains! Bottom line is that the combination of this scale and his thrower and trickler is worth every penny!
