It says it is accurate = to within 1/3 a graduation. It appears that graduations MAY be each 5 = grams. That means at best it is accurate to within 2 grams. But I think = you would be hard pressed to use it and compare your results with anyone = using a regular gram weight set. Especially when you consider the art of = setting the appropriate amount of weight on the key end and giving a = little bump to overcome friction and then watching to see a uniform = hammer rise. How would you watch a hammer rise with this gizmo? It = appears that it is only for static resistance, it cannot measure the = resistance of a key in motion. Spend the bucks and get a good gram = weight set. Pianotek has a real nice one for $125 on Page B-5. The one on B-25 is = for static resistance. No good for key down and up weight. I have Bill = Spurlock's which are also real nice. Pianotek's may be a bit nicer in = that they lock together when you need to have two weights on the key, = but I like my set just fine, thank you. I may have paid a bit more for = mine than Pianotek's. The other way to do it is to get the real cheap set from Schaff and use = an accurate scale to modify the weights so that they are actually = accurate. Much easier to just call Pianotek and order. Be aware though, = the instruments you have cited in your post are for static measurements = of resistance, not for anything that includes a dynamic form - like = weighting off a set of piano keys!
