Can anyone recommend a TDS meter. Didn’t want to spend a bunch, but also don’t want to buy twice. I just want to check some RO water I will be using.
Mine is a cheap one and has worked consistently well:
I reposted a different link. The Amazon link was for a different meter, for some reason. The current link is for the one I have.
Thanks Jon. I was wondering when I looked at the Amazon link it read in different units which was going to be my next question.
I have the same meter.
The listing below is from my order history, so I imagine it’s the same.

That’s the one I have also, on Hoosier’s recommendation.
I have the blue one also. 
Remember, TDS readings are truly an inexact science. There is low probability that the reading will be accurate since it is a rough correlation with conductivity that is used to predict TDS and conductivity varies with the types of ions present and their concentrations.
Therefore, its not truly important that you obtain accurate readings. However, its important that the instrument provides reliably, repeatable measurement. I don’t think that you have to spend a lot of money on a TDS meter to have a reliably repeatable instrument. I have HM Digital units, but there are plenty of others.
This one consistently gives me the same readings for each of three Glacier machines, respectively.
Bought this one http://www.amazon.com/Mudder-Digital-Temperature-Monitor-Quality/dp/B00MRLMG0M/ref=sr_1_4?ie=UTF8&qid=1447021494&sr=8-4&keywords=tds+tester+meter
$10 with free Amazon Prime shipping.
I’ve used it for a year now with no problems.
Thanks guys I just ordered the HM Digital EZ.
It’s read pretty consistently for me. Easy to use, too.
Hey me too! 8)
We should totally have a meetup for blue HM Digital EZ users at the next NHC. We can hang them from lanyards and makeup a sweet secret handshake.
Hilarious, I like it. And we could print up t-shirts with a Glacier machine on the front and “>25ppm Is A Deal Breaker” on the back.
I’m so disappointed. I followed one of Jon’s links about a year ago and bought a meter but it’s not blue! I feel so alienated, somebody please include me! [emoji16] [emoji12]
Mine is a HM TDS-4/TDS-4TM
I think that’s why they make ScotchBlue tape!
Thanks brewday! I just want to belong
Probably a lot like the famous Blue Coleman Extreme - just not the same. Operates on a whole 'nother level.
