What pocket TDS Meter?

[reefgeek84]

Does it matter what kind of TDS meter is good. I have seen some on ebay from 200-25 bucks, so does prive matter? and What do the nuimbers mean... Some are TDS1, TDS3, and TDS4? I am talking TDS meter to test my RO/DI water.

Let me know guys, I need to get one.
Thanks,
Brandon

I am using whatever one Walter includes when you buy a RO/DI from him. Don't have it handy so I can't tell you which one, but it is on his website:

I have a pocket one, but much prefer my dual in-line.
There are a lot of places that sell both.
I have this

And this
http://www.purelyh2o.com/cart.php?target=product&product_id=16&category_id=4

Both seem like good products. Order on-line and RC members get 10% off with coupon code RCDJB8HL.

Do you get the same readings from both or do they vary?

They vary slightly at higher (over 100 ppm) levels. Only a few % though.
