0.1 gram scale

December 31, 2008 7:32 PM

recommendations for a 0.1 gram accuracy scale that does not reset if you tare it to 0 and then remove the weight and has a capacity of more than 1kg?

I need a scale that can weigh in increments of 0.1g. It also needs to be able to display negative numbers. for example if I put a small tray on the scale and hit tare and then remove the tray I want to scale to display -0.56g of whatever the missing weight is. Most scales I have used just reset if they go into negative weight. I would also like the scale to have as large an upper weight limit as possible. 2kg would be good, more would be even better. Does anyone use or know of such a scale?

I do not know of such a scale, but I was scale shopping recently and found that Fry's has an excellent selection

Your profile doesn't say where you are, but VWR is a large supplier of laboratory instruments with branches in many countries. They stock many laboratory balances. You can have a look at the specs to see if any of these suit you. (I can't recall using a model with the features you request, but I rarely use high-capacity balances.)

Try Deal Extreme. I bought a lovely set of scales there for under $30 that do the negative tare thing (plus, for my needs, it measures carats too). I've linked above to the 2kg ones.

The only (consumer, anyway) kitchen scales I've seen that do .1g accuracy max out at about 250g, for what it's worth - e.g. Salter 1250. I think the commercial route is the way to go.

Cooking for engineers.... If you haven't guessed, my recommendation for a digital scale is the My Weigh i5000. (Still learning to use the thing.....)

I have a MyWeigh scale, although it's a 1g model and not a 0.1g. (It goes up to 7kg though.) It does the negative-tare thing; if I zero it with a 250g bowl on the plate, and then remove the bowl, it will display -250g.

I think they have several models which are 0.1g accurate, which they refer to in their literature as "balances" rather than "scales" (although as far as I can tell, they are not literally 'balances,' just more-accurate versions of the same stress-sensor digital scale design). My strong suspicion is that they would behave the same way mine does, and do negative values.

Your local "smoke shop and accessories" store will most likely have a wide range of scales to look at.

I forgot to add, my My Weigh i2500 does measure negative, but it only has a .5g accuracy

Seconding whoda--any smoke shop or pawn shop will have these by the truckload. example...

If you can't find what you're looking for feel free to send me Mefi Mail. I do IT work for a scale company that may be able to supply you with what you need.
