Looking for a digital pH meter. Is this overkill?

Seems to have the best reviews for that price range. The lower end models had very variable reviews - could be variable quality control or large amounts of human error.

What's the point of constant monitoring?

 

Is it going to your computer or just the display thingy? 

 

None of handhold type is accurate.

 

Even Pinpoint pH monitor, you need calibrate the probe everything couple months.

I even have ReefKeeper for my PRL tank.  :D

 

THIS IS ALL YOUR FAULT. I googled that and I want the herp version for my rotten little frog (who hates me and has been on a hunger strike). I need to wrangle a bigger raise.

 

Oh, well. Thanks, everyone! This will go on my wish list :P

Most items on aliexpress are counterfeits or pro copies of the real stuff.

 

I might be wrong but pretty sure Etekcity is the real manufacture of that product.

Also the link u provided states "Calibration: manual,1 point.(not included)"

Don't buy, it's total waste of money.

 

All handhold type is pretty much un-accurate and useless.

Any pH monitor needed to be able do two points calibration.

 

Single point calibration is just joke.

I use 4.01 and 7.01 all the time. I do it in every three months.

 

1, Clean, diluted HCl, 30 minutes

2, Restore, Saturated KCl solution, overnight

3, Calibration, 4.01/7.01 reference solution

Display thingy. heh  I like to have my ph a tad bit higher than my substrate pulls it to.  So when the ph drops too far, I adjust ph again.

Any reasons you would share as to why you do this?

Do you feel that keeping your substrate "working" has an effect on how long the buffering effects last?

I have tried the hand held PH meters - Paid like $100 for one.  Thought I kept it calibrated regularly.  But it was still way off compared to API liquid test.  Finally gave up on PH meters and went back to the liquid test. Easier and much more accurate.
