I have one of these and use it for measuring panacur for tortoise de-worming... I'm surprised everyone doesn't have one. |
| themadhippy:
Ive got a set similar to those for measuring white powder,and a freezer full of green leaf material.But having brewing salts and hops in the uk isn't illegal |
| BravoV:
For what ? Clearly ... obviously .. for you to spam general chat area. :-DD |

Well, I don't know, this one seems very small indeed. But I do have a small (but still larger than this) precision scale that can take up to 2 kg, and it's handy in your lab - when you need to accurately weigh components/boards with better than 1 g accuracy. 100 g max seems pretty low, but it could still find uses in your lab, for weighing electronic components, (small) boards, chemicals when you need to make accurate mixes, etc. |

Oh boy was I delighted when I could buy Chinese precision scales in, uhm, 2008 I think? Dealextreme was a fairly new thing, then I found out about Ebay selling this Chinese crap. (Crap being used in positive meaning, this is.) I got a 0.01g resolution, max 300g scale first, then a 0.1g resolution, 2000g one, and finally, a 0.001g 20g thing. All below $10 IIRC, and they all came with calibration weighs. None of them are as good as $1000 scales with similar specifications, but no ones expecting that. The bang-for-buck is great. Even the first one still works, after over 10 years of almost daily use. I check the calibration every few years. These seem to be repeatable, I would even dare to suggest accurate, to about +/- 3 least significant digits and have a minimum measurable offset of about 7-10 least significant digits. What for? Yes, I did some chemistry as a hobby and later professionally as well. Was developing films and built a motion picture film processing lab. Of course, for the short while as a professional motion lab, I mostly used prepackaged Kodak kit chemistry but I still mixed some solutions like black & white developers or experimental processing solutions from scratch. I also experimented doing the film itself, this is, black&white emulsions from scratch, using food grade gelatine, silver nitrate made from dissolving silver into nitric acid (beware: deadly gasses emerge!), bromide and iodine salts and some other special sensitizing agents I already forgot about. The combo of science + art of growing the microscopic silver halide crystals through careful process control (temperatures, stirring, chemical injection rates), affecting the film's sensitivity, graininess and resolution, was indeed interesting. A strange mix of very low and high tech, when you can produce a 100-megapixel equivalent image by a process consisting of only mixing basic chemicals. This is how it worked for well over 100 years - and of course, it still works. Now I mostly use the scales for weighing coffee. 24 grams per 0.5 liter of water, oh yes. |
