TDS Meter?
I am ordering an RO/DI unit from purelyh2o tomorrow. I have heard a lot about TDS meters. Do I really need one and if so which one should I get. I want to get one from purelyh2o since thats where my ro/di will be from. Which one should I get? Does it matter?

If you're cashless after purchasing the ro/di unit, don't worry about the TDS for a few months. A decent ro/di unit should carry you quite a few months, and you can buy one once your wallet recovers. Their use is simply once a week after you've been running quite a lot of ro/di to be sure the TDS is still zero. When it proves it's no longer zero, take your unit in for recharge, and forget about testing TDS for another number of months.
