Hi WW's !!

As I was hanging around here & there in different forums, I was wondering : which scale do you use ?

I have a Maul Tronic S (max 2000 g, 0 - 100 g d=0.5 g, 100 - 2000g d=1g) and a Tefal Sensitive Computer (max 5000 g, 0 - 1000 g d=2 g, 1000 - 5000g d=5 g)

:thanx:

I use the scales at my local Staples/UPS counter. :shock: Very accurate, and they don't mind me bugging them to use it since I'm a frequent customer there.

I just take a few bike parts with me that I want to weigh when I need to ship something or get supplies.

i have a scale up to 2000g in 2g steps. if i want to know the total bike weight i go to my lbs... they have a scale up to 10kg in steps of 0,1g :D :D

so i could see a difference before and after greasing the chain :D

but to my mind it is to okay to use a 2g step scale for parts and a 10 or 20g step scale for bikes

The important thing to remember with a scale that is only accutare to +-2g at low weights (sub 500g) is they often lack both precission and accuracey.

Any good scale for low weights should not only have high accuracy (ability to read fine increments) but also high precission (repeatability) for if precission is lacking then weights will not be correct.

I weigh to 0.01g and the scale is both accurate and precise to +-0.01g. With this I am confident I can weight the fingerprints on it, and do so repeatadly.

There is really no point for .01g accuracy. Those scales costs thousands. I think 1g is enough (on display) for ww.

Thats a dam expensive scale you have there. I have access to a very good scale in a chemistry lab. Even that is only accurate to +/- 0.02g

I agree, .01 g are not necessary.
But if you have parts >20 g (tiny items like cassette lockrings, bolts or some bottle cages) .1 g accuracy can make a huge difference in claimed vs. real.

I need a new accurate scale (up to 10 kg, steps of 0,5-1,0 g), but don't want to spend to much, any ideas? What are reliable options? Thanks!

I bought a Kern MH 10 K 10 lately. it goes up to 10kg with a reliability of +/- 10g. It cost ~40E. I think scales 10kg with an accuracy of 1g will be very expensive.

I reckon it's better to have a less accurate scale. I just shifted to a scale that can only weigh in 100g increments. I find it is better because then i become less obsessive and don't waste my money on parts that don't drop more than 100gs. So when I do spend money on light parts i know that i will actually be able to notice the difference.

I just bought a $20 USB scale that measures in 1g. increments up to 4540 g. Radio Shack. I've also got a small <120g. Vector VG-120 that claims 0.1g. accuracy. It was $60.

Hmmm, not necessarily.... With rounding error, you could be spending money and only saving 5g! You were just kidding though, rght?? :shock:
