I have been thinking about purchasing one of these Temperature/Saliniti/Specific Gravity Meter and I found two of them.
There is one made by JBJ that's a bit pricey.......

and then there is this other one that I found one ebay.

I wonder if any of you has this second one. I would like to know what you guys think of it. It seems tempting to buy this second as it is a lot cheaper than the one made by JBJ.
Thanks in advance.
cheers
