Product Details

Energy Saving Programmable Auto-Off If you've ever had your scale turn off on you in the middle of important measurements, you'll realize what a blessing this features is. You can program the EJ-303 to turn off automatically after about five minutes of inactivity or to stay on until you turn it off yourself.

Programmable Backlight You can even program the backlight for the EJ 303. 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.

Hinged Protective Windscreen When you're weighing with high precision scales like this one, even the tiniest breeze can interfere with weight readings. The A&D Newton 303 scale comes with a durable windscreen to keep out those pesky drafts. Oh, and don't worry, this scale makes it easy to put your items on, or take them off, the platform. Just flip it up.

Tare Feature The tare button on the front of the EJ-303 precision 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. 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, 200, or 300 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 EJ-303 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 & Adjustable Feet 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! The A&D EJ-303 is covered with a 5 year warranty from A&D Weighing against defects in material and workmanship.

What calibration weight is required for the A&D EJ 303? Is it included? Thanks
Asked by: DJB on April 13, 2020 6:02 PM
The calibration weight isn't included. You'll need a 300 gram weight with a tolerance of 0.001 grams or better.

Scale does exactly what we need. We are a seed company so smaller quantities of seeds we use in R&D we prefer to weigh. This is precise enough to do the task. Customer service has been great as well.

You will not find another scale of this quality at this price point. Old Will Knotts sells them at the cheapest price you can find online. Reading is steady. Measurements are very reproducible.

I needed to upgrade my simple jewellery scale for my perfumery. This scale is perfect for my needs and arrived in a timely manner. I had not ordered from OldWillKnottsScales before, but this was a good buying experience. The scale is very fast, I weigh in grams and it updates very quickly. It is probably a little more bells and whistles than I need at this point, but I will need those bells and whistles in the very near future and did not have to pay a fortune to get it. I would definitely recommend this scale. I chose Oldwillknottsscales based on reviews and did not want to do my usual buying for a product like this from a company that does not specialize. I am totally happy with my purchase.
