Product Details

Two Weight Displays? That's right! My Weigh designed this high capacity precision scale with two, bright, backlit weight displays...one on the front, and one on the back. So, whether you load the scale from the front or the back, you won't have a problem seeing your weights.

Rechargeable Battery Pack You won't have to worry about searching hi and low for a wall outlet to plug this scale into. The My Weigh iBalance i311 had an internal, rechargeable battery pack with up to 100 hours of battery life on a single charge.

Does This Thing Count? You bet it does! All you need to do is weigh a sample amount of pieces, so the scale can know how much each piece weighs, then start counting. You'll be finished in no time. Check out our i311 counting setup quick guide.

Stainless Steel Platform The i-311 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.

Protective Windscreen When you're weighing with high precision scales like this one, even the tiniest breeze can interfere with weight readings. This My Weigh scale comes with a durable, glass 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. The top and sides slide all the way back.

Easy Calibration To get the most precise weight readings from your scale, you'll want to calibrate it from time to time. This precision balance comes with easy to follow calibration instructions and a 200 gram F2 calibration weight to get the job done.Once you get a stable weight reading, use this feature to "hold" the weight on the display. The weight will stay on the display even if the baby you're weighing is a wiggly one :o) You can even switch through the different modes to see what your babe weighs in each unit.

Tare Feature The tare button on the front of this digital 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 items you're adding. This sure is useful when you want to use an expansion scoop to weigh your things.

Liquid Level Indicator This very handy feature will help you quickly and easily get your scale nice and level. It's important to keep your scale nice and level to get the most precise weight readings.

RS-232 Serial Port The My Weigh iBalance 311 has an 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.

90 DAY MANUFACTURER'S WARRANTY! If you have a problem with this scale, just send it to MyWeigh's warranty center in Phoenix, Arizona. They'll fix or replace your scale and send it on its way back to you within a week of receiving it. You should expect your replacement to arrive in about two to three weeks from the day you send the original off. Keep in mind that sometimes MyWeigh runs out of stock, which can cause a delay in the warranty replacement process.

Excellent Scale! Just What I Needed
review-star review-star review-star review-star review-star
As said in the title, it's an excellent scale that does exactly what I need. I'm in perfumery so this particular scale is great for (relatively) larger batch making within the lab or testing at the office with its 310g capacity. It has two, backlit panels so I can see the weight from both ends. Lastly, the calibration is easy enough and it's a workable size (not too bulky). It's just what I needed, thank you.

Just didn't meet my needs for reloading
review-star review-star review-star review-star review-star
I received the item and read the instruction that came with it (the worst instruction I have ever seen) I never could get it to weigh correctly. MyWeigh has no phone number to call for tech support so I decided to call Old Will Knott (very good customer service) A representative named Patty answered the phone and gave me some suggestion on things to try and even offered to send out a replacement unit. I decided to keep the unit and try one more time to get it to weigh things correctly. But the next day I decided to return the unit as it still wasn't right. After talking to Patty again she suggested the A&D EJ-123 scale. All the reviews I have read stated that the A&D EJ-123 was a good scale for reloaders and that is what I needed it for, so I purchased the A&D EJ-123 scale and Patty was sending me a return label for the i311 scale. I have received the A&D EJ-123 scale today and it seems to be a much better scale ( with great instruction booklet) and should work fine my needs. I which I would of taking another person advice and called Patty first before buying the i311 because it would of saved us both a lot of time and money. Thanks Patty for all the great customer service you provided me. CALL THEM FIRST they know there scales!

Didn't work for me for reloading.

The set of scales I purchased did not meet my needs for reloading. This set of scales has an auto stabilization function that will not allow it to weigh individual pellets of powder. If you are looking for high accuracy powder measurement, this is not your scale. However, I returned the scale and they recommended the A&D Newton EJ-123 High Precision Portable Scale and it works great. The return was quick and easy. If you are looking for a reloading scale, call them and talk to the tech. guy before you buy. It will save you a return issue. Great company and I will buy from them again....after I discuss my needs with them.

My Weigh iBalance 311 Scales
review-star review-star review-star review-star review-star
I shoot long distance (1000 yds) rifle competition and having a set of reliable scales that will weigh out to .00 of 1 OZ is absolutely critical. I recently purchased the iBalance 311 scales and now am able to weigh everything I use in reloading reliably. The scales are moderately easy to use, very reliable in consistency and the price range was acceptable on a retired fixed income budget. Other shooters might want to look at this set of scales more closely. jb
