Product Details

Energy Saving Programmable Auto-Off If you've ever had your scale turn off on ya in the middle of important measurements, you'll realize what a blessing this feature is. You can program the i500 to turn off automatically, or to stay on until you turn it off yourself.

Really Cool, Reverse Lit Display The i500 has a bright, reverse lit display. You'll have no problem reading this precision scale, even in the dimmest lighting.

Does This Thing Count? You bet it does! All ya 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.

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 if ya want to use this scale as a diamond or carat scale for weighing your jewelry pieces.

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.

It Remembers The Last Unit ya Used If your application needs weights in the same unit of measurement, (like ounces for instance), it can be a real pain if your scale always turns on ready to weigh in grams. It's a good thing the iBalance 500 turns on displaying the unit of measurement you were using when ya turned it off.

It Has WeighMeter™ Technology! If ya put too much weight, (more than the capacity of the scale) on any scale it can cause permanent damage. Unfortunately, most scales warn ya of an overload after it's too late. Luckily this precision scale comes with WeighMeter Technology to tell ya when you're coming close to the maximum capacity. This will save ya from overloading your scale and damaging it beyond repair.

Easy Calibration This scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the i500 comes with easy to follow calibration instructions. You'll just need to pick up a 500 gram calibration weight to get the job done.

Kill Those Vibrations With VibraKill® Did ya know that vibrations can cause a scale's reading to bounce around from one weight to another? Included with this digital scale is a VibraKill® Pad to keep vibrations, (caused by everyday items like, your fridge, nearby music, your washing machine, etc...) from messing up your weighing.

30 YEAR MANUFACTURER'S WARRANTY! If ya 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 ya 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.

Just Right 5 stars

Works as advertised. Thanks to Old Will's help in selecting this scale, I could not be happier with performance. Used to weigh companion birds (parakeets and conure). 500gram capacity is plenty for accurate weighing of each bird and perch (perch not included with scale purchase). Would not have needed the 0.1 gram precision, but it came with this scale and for the price I am not sorry it weighs to that spec.

Great for soap! 5 stars

Not the exact scale I wanted, but the best I could afford. The high resolution is great for measuring lye. I love that it comes pre-calibrated.

Great Scale 5 stars

Great scale especially for the small cost. We use this scale for "counting" more than for weighing. It is easy to set up and very accurate even for lite weight pieces. As a weighing scale it measures to .000 which is a little too precise for our needs so we use the I2500 and the WR12K. Old Will Knot & My Weigh are a great team and My Weigh stands behind their 30 year warranty. We have been using their scales for close to 15 years and have no complaints.

Great Scale 5 stars

This scale is worth the price. I have used it for a couple of weeks now, and it saves me time. I use small silver beads and tubes in my jewelry making, and need to count them for inventory. The count feature on this scale is on the money. I had beads that weighed .65troy oz. and needed a count. Put 50 on scale and set count feature, added all but 10, scale listed 763, added the 10 and it went to 773. Love it.

Great scale 5 stars

Perfect little scale to count tiny elastic bands used by show dog groomers that we sell in our business. The scale is accurate and its features are easy to use. The price is reasonable and the service was great. I especially like the AC adapter to avoid using batteries when possible.

Better than expected 5 stars

I felt like I was dealing with a real friend over the net at this site. The scale is so sensitive and accurate that I had to turn the fan in the room off for the scale to rest on zero. Excellent value and perfect for use in it's range. Will definately buy from this company again. Thanks so much.

Excellent scales 5 stars

I'll have to say, I have never encountered quite the feeling of personal attention anywhere else. The scales is exaactly as advertised, VERY accurate, and all the features that I could ever want and more. I'm VERY happy with the product, the fast delivery, packing, and all around service. I also bought the 500g weight and it was interesting to use for checking accuracy but it really isn't needed. The scales zeros and sets the range automatically and is right on the money everytime.

Questions and Answers

Q: I'm looking for an extremely accurate scale for reloading. This one is quite a bit cheaper than those sold for that very purpose. I have purchased and returned a few digital scales because they would not stay accurate and consistent. Obviously, bad powder weights can result in serious injury or death. Will this one fill my need? Asked by: Stitch (11/19/2015) answer this question

A: Hi Stitch,

Thank you for your question. Unfortunately, we're unable to recommend any of our scales for reloading for the reasons you mentioned. As for this scale, it is inexpensive because it only measures in single grains while most reloading tools measure to at least 0.02 grain.

Take care,
