No, they probably can't. Good digital scales generally do cost a small fortune - well, £500.00 or so. Still, that's better than a few years ago, when you couldn't access Magnetic Force Restoration technology for less than about £1000.00. I have digital balances ranging from Good to Very Very good, but if I could only keep once balance for the rest of my life it would have to be the beam balance.jimmyhall wrote:Can anyone recommend a good digital scales, which dosn't cost a small fortune or a day to set themselves up
Cheap digital balances usually use strain gauge measuring, which is really at the limit of the technology when used at the resolution required for weighing charges accurately. They suffer from drift, slow settling and particularly from poor response to small changes (i.e. when trickling the last few kernels of powder). It is common to hear of people having to dab the powder pan with a finger to create a larger disturbance in order to overcome the heavy filtering which is the only way to keep strain gauge balances stable and not drifting at that kind of resolution. This is not conducive to precise measurements, and explains why this sort of technology has no place in labs.
If you still want a recommendation, I suggest the A&D FX-120i. You can read lots of opinions about them here.
