A hydrometer or refractometer, do a google search and you will find plenty! The general concensus on here is a refractometer is well worth a little extra money, about $50 compared to $8 for a hydrometer, but you get what you pay for! There are all sorts of horror stories about hydrometers not working right and reading wrong. Well worth the investment in my opinion, we have way too much money and time wrapped up into our tanks to take a $40 chance on a cheap peice of equipment!! Here is a link to the refractometer I have:
Premium Blue Refractometer - RHS-10ATC: Premium Aquatics
There are a lot of high quality refractometers out there, but if you decide to get one make sure it has ATC (Automatic Temperature Compensation)
