Precauciones
1. Manejado con cuidado y cuidado a la ligera.
2. Se mantiene correctamente y no debe colocarse en un ambiente húmedo y polvoriento.
3. Úsalo con pinzas o guantes. No toques con las manos desnudas.
4. Cuenta la cantidad para evitar perder antes o después de usar. La funda de plástico es muy útil para almacenar los pequeños.
5. Limpia el polvo en la superficie con un cepillo para polvo suave o un paño de limpieza antes de usar.
6. La temperatura de los pesos debe ser la misma que la temperatura en el laboratorio.
La diferencia entre los pesos de clase F1 y clase M1
1. F1 es más preciso que M1, con un error de permiso más pequeño.
2. F1 utiliza acero inoxidable 304, M1 utiliza acero inoxidable 2cr13.
3. M1 es con barra de ajuste (en la parte inferior de los pesos), F1 está sin.

I like this set. It let me know my scale was good and didn't need professional calibration so it was well worth the money. I use my .5ml weight the most to test for accuracy of my scale.

Weights appear to be of high quality and accurate. I weighed them on an OHAUS Analytical Scale with readability up to 0.1mg. Before testing these weights, i calibrated my scale with ANSI Class 1 weights. On my scale, everything up to 5g was dead on accurate. The 10g weight was off by 0.1-0.2 mg, the 20g weight was off by about 0.2mg, the 50g weight was off by 0.4mg. These are definitely class F1 weights with everything up to 5g being closer to class E1 grade so these are nice weights for the money. they can be used to calibrate anything up to 0.001g but for the 0.1mg precision, you may need to step up a class to get the best calibration possible. I was not able to test anything higher than 50g because my scale only goes up to 60g. I Would assume that each successive weight after 50g has double the error of the previous weight. So a 100g weight would have an error of 0.8mg and a 200g an error of 1.6mg but again, I could not verify this. This is all to say that these weight are just as accurate as my ANSI Class 1 weights but at a fraction of the cost. If you are looking to calibrate a high end analytical balance than i would say that these weights would work for anything up to 5g. Going higher than that may throw off calibration slightly but if 0.1-0.5mg (0.0001-0.0005g) of inaccuracy is alright for your applications than these weights are for you and I wouldn't fork out hundreds of dollars on OIML Class E2 or ANSI Class 1.

The weights appear to be made from quality stainless steel polished to a mirror finish. Very little attraction to a strong magnet backs that up. I only have a very old but well cared for Mettler H10 analytical balance that measures down to 0.1 milligram. I can not use this scale to verify the accuracy of the weights but I can use the scale to compare weights to each other. The scale (when used properly) is extremely sensitive to minute changes in weight. Example 5 gram compared to combined 1, 2, and 2 gram weights. Doing several of these comparisons, paring up different weights showed absolutely no distinguishable difference. I know this does not verify the accuracy, but it shows that their relative values are very consistent. This suggests to me that they were carefully tuned and therefore are likely to be very accurate. I was only able to do these comparisons on the weights 100g and under as my scale maxes out at 159g. Overall this set is impressively high quality for the money. I don't normally write reviews but just had to share what a great value this is.

Nice set for the money assuming it's as accurate as it claims.Tweezer are metal instead of plastic which could cause damage to the smaller weight. Comes with microfiber cloth.**NOTE** everything that isn't a number or 'g' for gram is in Chinese, so the certificate for this is somewhat suspect, and difficult to trace or verify. F1 without a traceable calibration authority is suspect at best. then again if you look up how much a "real" F1 set is, this is a great deal.
