I'm having a problem reading my PH level from those color charts.
Wondering if I should get PH digital tester.
Could you recommend one?
Do they really work? Are they accurate?
Are they a hassle to keep and how much is maintenance cost.
Would really appreciate info

tks

Raul,

They do work well.

I use a Milwaukee brand SMS 122 ph meter to drive my auto c02.

I have had it for over 3+ years and is still accurate. I replace the probe annually just in case and I calibrate every 2-3 months to ensure accuracy........... I would recommend this brand.

Do some web research on ph meters and you can see the variety, price, etc.

Here is a link to the meter I use:

Automated Aquarium Systems - SMS122 pH/CO2 Controller

Please note that prices on the web vary widely. Find the model you want, and then search for the best price.......

I have seem my meter from $80 - $150 usd...........

Best of luck

Raul,

Actually, I was just thinking of selling my pH and TDS meters, as I have "upgraded" to one that does pH, TDS, EC and temp (I'm lazy and I was not using my multiple meters ).

I have to double-check when I get home this evening, but I'm quite sure that the meter I have is the Oakton pHTester Basic, and my TDS meter is the Oakton TDSTestr. I don't see mine on their web site, so it might be the a previous model (say the model 10, rather than the current 11).

Both have worked quite well for me, and can recommend either.

And if you're interested in a very slightly used pH meter, shoot me a private message.

You can easily make a ph tester with minimal cost. Here is all the info you need.

hope this helps and saves you $$

Does this work with any pH probe? It certainly looks like a cheap way to go.

I believe so, i am acutually buidling the more complicated one listed on that site with the auto shutoff valve for a circuits class im taking

They make some cheaper pen types that do pretty well, if you want a nice pH probe type, the Hanna is good and you can run other probes with it as well(comes w Temp+pH but you can add any ISE or Redox etc).

Pinpoints have been used for many years in the hobby, decades I guess now....
