Bonvoisin Lab Analytical Balance 500g x 0.001g Precision Digital Scale .001 Gram Accuracy Laboratory Scientific Milligram Scale 17 Units Selectable

Nice, Reliable, and good Performance. Thank you

It arrived in a box with a 200g weight bouncing around inside. The screen was scratched and dented. I have a very precise weight set and the scale would give me a different weight every time I zeroed it. It is advertised as being accurate to .001g, it wasn't accurate at .03g. That is a big difference!!!! There was no manual. Looked like it had been returned before and just thrown in a box for the next person (me) to buy it. Horrible!!!!!!Edit- The item I received was a return to Amazon, not to this company. The company reached out to me and made it right. The scale I received from them was packaged perfectly and there was no damage. I checked it with my precision weight set and against my other scale, which cost 4x the price, it was right on the money. This company did an excellent job at going beyond expectations to make it right!!! This is the reason I have increased my rating to 5 stars.

great scale but not what i was looking for. worked as told and felt like a reliable scale. only reason i retuned it was because it was a little too big for me. I like the pocket scales better.

I have noticed that the scale does not seem to function properly, as it consistently drifts, making it unreliable for accurate measurements. Additionally, the design of the windscreen is quite problematic; it requires the user to either operate the scale without the windscreen or to repeatedly attach and detach the windscreen after every sample, which is highly inconvenient.I previously contacted customer service regarding these issues but, unfortunately, I have yet to receive a response.This thing is trash do not buy. I will be returning.

So far the scale is working great. I use them for reloading. I will say they are very accurate they might be a little to sensitive for some. I contacted the company and had a fix for the over sensitive scale. The next day. Great customer service and so far a great product. Build quality is very good

The product met all my expectations and needs for my experiment It is quite precise and easy to use. It’s exactly what I needed for precision reloading. Calibrates very easily.

I ordered this precision balance for my daughter, who is currently studying high school chemistry and has a proclivity for data analysis. While this scale is much more precise than she currently requires, it will be increasingly valuable to her as she continues her studies.This has several features that we are already appreciating. First, the accuracy is astounding. With a sensitivity within ten thousandths of a gram, this scale can easily measure a single grain of salt or any of the other solids she uses in her experiments. Second, it can be programmed to display seventeen different units, so we can measure just about anything including evaporation, mass, etc. Third, the RS232 interface will allow us to plot data electronically. We haven't yet used this feature, but will likely in the future. The rechargeable battery is a huge plus. We can use this scale anywhere, including outdoors. Finally, for a precision instrument, this is very easy to calibrate with the push of a button. It comes with a 200 gram weight for calibration purposes.There are several downsides to this scale such as the requirement to power it on and allow it to sit for fifteen to thirty minutes prior to use. Also, a RS232 cable isn't included, but they are easy to obtain.Otherwise, this is a great instrument.

An excellent addition to the lab, but mine did not include the charger cable, and there's no mention of the DC voltage for the normally provided one. Could anyone let me know ow what voltage the barrel-jack power cable is on the one they received?
