Can this scales get certified? where do you send it for calibration?

We use it for weighing fish in a local competition and rely on its calibration by weighing a known fixed weight before each weigh in; ; It varies ever so slightly each time probably due to wind or weather, but for the purposes for which we use the scales this doesn't matter. We dont know anything about certification as we dont require the scales to be certified by any organization.

Here in South Carolina the State Dept. of Agriculture Certifies scales annually. Pass or fail. If they fail, its up to you to send to manufacturer for certification. And they only do this on routine inspections for bussineses.

I can't say for certain if a scale such as this can be certified. It has no adjustment that I'm aware of so if it needed to be calibrated, I don't know how it could be achieved. If I were you, I would search online for companies that do this type of certification service and inquire with them directly.

There is no initial calibration needed and I don't find anything regarding instructions on how to calibrate it should there be the need to in the future. I am assuming that since it works as most digital scales do, measuring changes in electrical resistance distributed to load cells, calibration is performed at the factory and would need to be performed by the factory in the future if there was a need to do so. I have had other digital scales which operated the same way and lasted for many years. It measures the same as a mechanical scale I have so I believe it is accurate from the factory. The only way to tell for sure is to locate a standard and periodically check to ensure it is calibrated against that standard.

I did not know for sure myself, so I contacted the manufacturer. They got back to me within a day by the way, very fast. I was told that these particular scales have no need to be recalibrated. They were very concerned why I was asking and asked if I was having problems with it. I told them no just wanted to know how to recalibrate it. If I was having problems with it they were quickly going to replace it. I was impressed, seem to be a good company that is wanting to make sure their customers are happy.

No, you do not have to calibrate this scale. It work great just out of the box. I highly recommend it!

During the calibration procedure it only asked for the 200 gram weight, not the 100 gram one, so I don't know what others are talking about. BTW, I spent a bunch of time calibrating this down to .01, only to realize that it will vary depending where on the scale platform you place the idem being weighed, so it's kind of a waste of time.

I guess by using a known value, like the calibrations buffers, 4.0 or 7.0. It's like using a calibrated weight to check a scale

any scale can be at sometime. Have you been stepping on it so it registers some weight, then stepping off and waiting until it zeroes? That was my original mistake...not doing this. Was about to toss it, but now it works fine and is consistent

You have to check the instructions that came with your type of scale. You may also call their service dept and they might help you. Check on line if you do not have the instructions. Good luck.

I have no way to verify accuracy since I don't have nist traceable standard weights. Precision seems OK. I have noticed that the scale sometimes doesn't want to zero. I'll turn it on and it moves away from zero (I have seen it go higher and lower). When it does this the zero may wander as much as 10 lbs. Eventually the scale stabilizes. I have not contacted the mfg. I find this annoying but am willing to live with it since it rarely happens.

If by calibrating you mean bringing the scale at 0 when you place on it the container in which you wish to weigh something, there is a button that calibrates the scale at its touch. It's user friendly...

If you're in the U.S., the answer is NO. This scale, as with most inexpensive scales, is not certified legal for trade. Scales used in trade, where a business charges customers for a service or product by weight, must be inspected and certified by the state where the business is located. Hefty fines are levied for using non-certified measuring equipment, and the fines are much more than the cost of a good NTEP approved scale. Don't risk it.

Not sure...I imagine it has some sort of warranty. But I will let you know that I am very pleased with this scale. Glad I bought it.

I purchased this scale as a teaching tool. Since receiving your question I have been using calibrated weights to check accuracy and it has been spot on. I have also rigged an apparatus that allows us to weigh odd shaped items such as a flake of hay and I have found this scale to very handy in the barn. I do not know how to calibrate it and it is clearly marked "not legal for trade" I hope this is useful.

Mine arrived perfectly ready to go. No calibration needed. Great scale. Works perfectly for my needs and looks sleek and modern.

I don't know why you would require certification but these gauges are not NIST certified. You can calibrate them, though using a dead weight tester and the adjustment screw in the face of the gauge.

No it doesn't come with a weight for calibration. I use a US coin to help me calibrate. You really don't need one for this scale.

Not that I know of. I was able to return this scale. It's the worst one 've ever owned. It wasn't accurate at all after a couple of months.
