Product Details

Programmable Auto-Off Feature If you've ever had 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 Newton balances to turn off automatically, or to stay on until you turn them off yourself.

Programmable Backlight If you've ever had 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 Newton balances to turn off automatically, or to stay on until you turn them off yourself.

Hinged Protective Windscreen You can even program the backlight for the EJ123. If you work in dim environments, you can set the backlight to always on, or to turn on when you press a button or change the weight on the scale. If you don't really need a backlight, just set it to off. No unnecessary power use here.

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 item you're adding. This sure is useful when you want to use a separate weighing container or get the weights of separate items.

Stainless Steel Platform This compact digital scale 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. This scale's platform is perfect for weighing smaller items. Use it as a jewelry scale for weighing small gems and jewelry pieces, or as a counting scale for pharmaceutical measurements... the uses are endless!

Easy Calibration You'll have no problem at all calibrating this portable balance. You'll just need to pick up a 100 gram calibration weight to get the job done.

Does This Thing Count? You bet it does! All you need to do is weigh a sample amount of pieces, so the EJ123 can know how much each piece weighs, then start counting. You'll be finished in no time.

Easy To Clean, Sealed Keypad You won't have to worry about dust and dirt getting stuck under and around this scale's buttons...The A&D Newton has an easy to clean membrane keypad with accurately labeled keys for easy weighing.

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

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.

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
I live in Virginia. What about humidity issues?
Asked by: shinydime on June 26, 2018 3:14 PM
Answers
Good question. Any precision scale can be affected by the environment in which it's located. After you receive the scale, you should allow it to sit for about 24 hours so that it can acclimate.

Question
will this work good to weigh diamonds with it? is this accurate enough to weigh 0.001 ct ?
Asked by: aslanian86 on March 23, 2017 1:36 AM
Answers
The EJ-123 has a resolution of 0.005 ct. It will work well for precious stones and such, but if you need a higher resolution, then you may want to try a different scale. At the bottom of our site under SHOPPING HELPERS, you can use our Scale Finder to help you find the right scale for your needs. You can also call us if you have any questions. Thanks!

OK here goes; I do ballistic load development for antique firearms as a hobby and needed to replace my failing bench scale of ten+ years. My research for a better quality, and hopefully more reliable scale to fill my needs, led me to the A&D Newton ej123 bench scale, and at a respectable price point from the folks at “Old Will Knott Scales”. Turns out my experience with both the product and the vendor has exceeded all of my expectations, 5 stars-plus. Now if I can only get these types of results at the Range!
Thanks to the folks at “Old Will Knott Scales” for doing what you do - better than the rest.

Let me start by saying, order from Old Will, do not use Amazon. 3rd party sellers will be ready screw people over and very much so out of someone who worked hard for the money. I ordered the same one from Amazon and let's just say it was missing the metal platter. Let alone the seller claimed it not to be open. When the tape was cut before.
Now ya see the back story of why I have ordered from here, good company, honest, and I had a good chuckle at the paper they leave in the package. Sorry, only way to know what I mean is to order from them.
The scale is great for reloading, as it can read one kernel of powder, which isn't super important, but when loading near max charges...rather be on the safe side. Word of caution, don't have any fans on when using the scale, it is super sensitive!

I bought this scale as an upgrade to my rifle ammo reloading process. Previously I was using an 15 year old Dillon electronic scale but it only measures to the tenth of a grain and I wanted more precision for powder weighing. This measures to the hundredth of a grain. (It will actually measure a single stick of powder). I've only had this scale about a week but so far I am impressed. Once I got it leveled, its been great. I was concerned about how long it would take to settle on a weight but it is fast enough and I'm not a patient guy. Relatively simple to use with good instructions. If you are a reloader, this can up your game!

Absolutely great experience and product. Super fast well packed shipping. Cheapest prices and widest selection of balances and scales I have ever found. All the reloaders looking for accurate, stable, no creep, .02 grain resolution this is it. This scale will trickle individual kernels of extruded powder all day long. Why there is not more cross over of this site and scale in the shooting world I will never know. Almost none of the standard name brand reloading scales have this capacity and cost the same or more. I regret playing around with anything else knowing now what great equipment is.

Thanks Old Will Knott Scales.

We needed a scale to weigh in the +/- 0.002gm range but not very often, so we did not want to shell out beaucoup bucks. This scale is perfect for the price and precision. I am glad it did not have a huge "box" of glass on top, but did come with just a little breeze shield on a hinge--easier to use and lower profile. Glad I found you on the web!

Excellent for a strain gauge scale
Rating:
review-star review-star review-star review-star review-star
Used for reloading i was able to get repeatable accuracy to +/- 0.02gr though it is a slower process than I would have liked getting there. The slow response to change in weight is not a function of the manufacturer, but of the strain gauge scale and the fine increments it can read. I threw 100 charges to within .02 of my goal and then put them, randomly, back on the scale and they were all within that tolerance. The scale does drift, again, a function of a strain gauge scale, but for the price OWKnott offers it is tough, if not impossible, to beat. I will be saving my shekels for an fx120i and an auto trickler, but for now this scale fits the bill.

The scale performs well, my standard weights were spot on out of the box and calibration was not needed. It does take a couple seconds to stabilize but that is due to the older technology used. The much better force restoration scales cost twice as much, this one is good value for the price.

My only complaint is it feels a little flimsy, not as solid as I would like. But it is a precision scale, not for heavy duty use so it should not matter in the long run.

Seems to be very accurate. It takes a little time but you must wait until you it stabilizes each weigh. The zero drift makes me a little uneasy, so you must keep an eye on it and re-zero when needed. Don't worry about the last digit drifting up and down 1 unit, it is the nature of the beast. I had to buy a line filter at Best Buy which raised my cost 75 bucks. It keeps it's calibration quite a while I just wish it was more stable. Using the wind cover is a must. Ray

After trying a less expensive high resolution scale that did not perform as expected the Old Will Knott staff happily accepted the return and suggested this scale. For only marginally more money this is a completely different class of equipment. I am now able to weight essentially down to a single grain of powder and easily achieving single digit SDs without all of challenges of the cheaper models. If your unsure this is the one don't waste your time on anything cheaper.

I ordered this scale to tighten up my groups at ultra long range. Shooting past 2000 yards everything needs to be consistent especially the powder charge. I found that my electronic powder scale and dispenser was fine for regular distances but not accurate enough at ultra long ranges. Now I use the powder scale and dispenser to start, then I finish using the A&D EJ-123. My groups have improved along with first round hits.

I figure this cost me an extra $150 because of my stubbornness. In spite of the mixed reviews on the Gempro 250 I bought one last year. After trying to keep it weighting over the past year it finally died. This unit so far is far superior. I use it for reloading rifle bullets and the repeatability of this scale is great. The % function makes sorting brass quick and easy. The hole in the lid allows me to add one kernel of powder at a time to get right to the load I'm looking for. I'll come back in 6 months or so to report on long term dependability.

No matter where I place the pan on the scale head it weighs the same and does not bounce back and forth. Once I obtain my desired weight I don't have to raise and lower the pan to verify it is accurate. Couldn't be happier thanks once again for the advise and outstanding product.
