[Help] Electronic Weighing Scale

[Phang]

I need to use an electronic weighing scale to check the weight of new piston sets.

 

Accuracy to 0.1g is good enough but preferably 0.01g so that I can weigh the wrist pin, circlips and piston rings too.

 

I am willing to pay a small fees to use the scale, I need about 10 minutes (probably less) to weigh 2 sets of piston.

 

Any lubang, contacts or suggestions are greatly appreciated

Thanks bro, 1g resolution is not good enough. The weight of each piston is 375g and the maximum allowable difference between pistons is 1.0 g for this particular set.

 

I've got a few suggestions from friends, jewellery shops, traditional chinese medicine shops, school labs etc. I'll see if I can convince one while carrying a box of pistons

jewellery shop/lab is best..sure have what u need

500g @ 0.1g

100g @ 0.01g

how much you bought it?

 

Total about USD$50

.01g/375 x100=.00266 percent accuracy??

 

wow...your bike will be the best balanced...

good luck to your project..

Bro, that's static balance.

 

I just did a quick calculation, the piston of my bike at 6,000rpm will see 2258G (G force) of maximum acceleration and deacceleration.

 

Any difference in weight will be multiplied by the G

 

Don't play play ah

Good to find such useful scale with a small budget. In USD$50 These are really surprising one.

I found some more digital scales as i was searching about them to have a good one.

Try searching in Taobao..u should be able to get good deals as most of these low resolution scales are made in china.
