Refractometer suggestions
Hey guys.
Any advice RE purchasing a refractometer? I've noticed a wide range of prices, but am thinking that I don't need the 'best' one around. Any good leads or info regarding this? Thanks, Matt |

I got one last year from NaturalCheck.com for about $40 and am completely happy with it for my need which is just for my home use.

Primarily for measuring the sugar composition of tomatoes....selecting parents, offspring, etc. Also good for monitoring changes in the garden as a whole.

"Gardening in the Green" or "General Discussion" forum would have been better suited for this topic. Here is a link for a introduction to Brix. Ami

Have you Googled "used laboratory equipment"? I found a really good refractometer (the classic kind we used in chemistry labs as undergrads) sitting unused in a department here and they just gave it to me (for work use). Some of the newer versions are really cheap and funky.

I just ordered one from the source Kath listed since I have been meaning to buy one for 2 years now. I ordered on Thursday night and received it Saturday morning! It looks like a good quality built one, too.
