Bonvoisin Lab Scale 5000gx0.01g High Precision Electronic Analytical Balance 0.01g Accuracy Laboratory Precision Digital Scientific Scale (5000g)

I'm a little confused about how to rate this. I wanted to buy a 500-g capacity balance. The one I got came with a 500 g calibrated weight...but the balance only goes up to 322 g because the tray weighs 178 g. Technically it goes up to 500 g if I remove the try ..but no one ever does that. Therefore, the description is misleading. On the other hand, this is not a big problem because I do not have to weigh 300+ g, so I decided not to return this. The balance is accurate to 0.05 g (my lightest calibration standard), which was surprising. It's easy to level, it's not very heavy...So, overall, for $111, and for my needed accuracy, I am very satisfied with this instrument. 👍

Good quality for price

I could have sworn I already reviewed the Bonvoisin Lab Scale 5000gx0.01g High Precision Electronic Analytical Balance 0.01g Accuracy? Anyway, it is Fantastic, almost unbelievable. It is incredibly sensitive and has a huge capacity. I am using it in the kitchen for precise measurements of food calories and nutrients. You can put an entire heavy cast iron skillet on the Bonvoisin, tare (zero) the scale with one button push, and then add your food and it will read out the amount of food to ±0.01 grams. When making a salad, I place the bowl on the scale, tare it, add lettuce and record the value, tare, add tomato, record, tare, add broccoli, etc. I later enter all values into a custom Excel spreadsheet and determine my exact calories, fat, carbs, protein, and other nutrients for the day. It was very revealing as I found most of my calories were coming from the Olive Oil dressing and the Red Wine I was drinking with the meal. I cut back on Olive Oil and reduced number of glasses of wine. This is a great, convenient scale with high capacity and high precision.

Overall this seems like a nice quality, affordable scale with apparently good precision. I would buy it again ...probably. The reason I can't give five stars is because the "percentage" unit function is very NON-intuitive and isn't covered in the manual at all. This was particularly important for me because I bought this scale to accurately mix epoxy and also body filler for a car project and I was excited about using the percentage function extensively, in particular. Anyhow, after about two hours of trial and error I figured out the 'secret handshake' to make that function work. Here it is: 1) Click "units" to find the one with "g" AND "%." (not just "%".) 2) Press "cal" once, briefly. It won't beep or blink or do anything satisfying. 3) Place the first item on the scale. It'll read a weight. Leave the item on the scale. NOTE: DO NOT PRESS "tare" ON THIS SCREEN. 4) Press "units" a bunch of times until it gets to just "%" (no "g".) It'll say 100 meaning 100% of the item still on the tray. 5) Press "tare" now, only on this screen, only after the preceding steps. Add your second item. the number shown will be the percent of the new item compared to the first item. For body filler, I do step 1 and 2 and then plop a blob of filler on the (protected) tray then do steps 4 and 5 and add catalyst until I hit 2% which is the target for that particular body filler. Easy as that(!?!?) It's NOT intuitive but it works beautifully and gives very consistent mixes. Hope this helps someone. :-)

Using it every day, it is just perfect!!

Had issues with the first one but they were really good to reach out to me. Hopefully the new one will work better.

Bought to measure the weight of precipitation in a rain gauge. Really wanted to like it, but after 200 or so measurements the scale started to vary too much. First I had to weigh the rain gauge components so when the precipitation was collected in he gauge, the difference was the actual weight of the precipitation. While weighing the gauge components, the scale began to vary well over the stated +/- 0.03 grams. I could live with the stated variance, but it soon increased to +/- 0.1 gram and higher. I thought I might need to re-calibrate the scale every morning (after a 30 minute warm up) using the 2kg weight, which I purchased separately, but after less than 10 uses, the variances began again. There were a lot of great reviews for this scale, but almost all the 1-star ratings mentioned the non-repeatable weights for the same item and the non-acceptability of the variances. I bought this scale to increase the accuracy over my current scale that measures to 1 gram. This product will be on its way back to Amazon tomorrow. By the way, the scale was packaged great.

Great scale! Very accurate.
