Digital pH meter

[Mr Good Cat]

I never used digital pH meter and did it manually with litmus.
Now I'm curious, if it worth to use such kind device to control pH continuously while base acidation in progress?

Mr Good CatYes but must be with glass electrode.

Yes but must be with glass electrode.

btcboss2022As I understand, mostly it is metal, glass and PTFE?
PTFE should be also neutral?
Is there anything else to pay attention while buying? I see the price range vary from 40 to 400 EUR.

Berlin777Glass, forget all other options and less than 100€ not recommended normal price for standard quality with glass is round 180-200€

btcboss2022It was for £180 and the probe dissolved, but it’s not proper chemistry one just for my plants

Now using the paper strips. The annoying thing is when it comes to the pH meters they need to be calibrated frequently

Berlin777I can get a very good glass one for you . Also they have ph control systems all for lab use where I am. Some apply the acid for you, they and monitor both temperature and pH lvl. Some only monitor the pH lvl and temp. U can also choose options that can alert to your phone.

I get good lab acid rated ones here for under 100 pounds. Also I bought a ph controller system. It adds the acid drop by drop untill it reads 5 or 6 or however much number I set. It can also send me a message to my phone. Haven't used it yet as it's on the way but. It also jas a second pump to raise the pH lvl if for some reason it drops below what I want it can add another liquid to raise the pH lvl.
