Milwaukee vs Pinpoint PH Monitor/Probe

[Shawnna]

Does anyone have any insight as to which PH monitor/probe is better - Milwaukee or Pinpoint?
Thanks!

Don't have an answer for you.Would just like to tag along and see what others have to say.

Im using pinpoint and I'm pretty happy, but I need to check for calibration again...

Not wanting to appear too stupid here but.......

what does "calibration" mean with respect to a pH monitor? Here's my best guess.... the calibration solution somehow allows you to "set" the monitor to give you as accurate a reading as possible, right?

If this is accurate, how often do you have to "calibrate" it?

Thanks again for your response and patience with my obvious ignorance!

Shawnna, I believe you're right about the calibration. I don't have a probe myself, but they do need to be calibrated to a certain pH periodically in order to give accurate readings. Hopefully someone with more first hand knowledge than myself will chime in as to how often they need to be set.

I use a pH probe on my aquacontroller. I calibrate it every 3 to 6 months. You use calibration fluid. A 4 pH and a 10 pH ... others use a 7 pH and a 10 pH for calibration. You calibrate using both indicators and then the unit will use the two data points for the calibration of the probe. Does that make sense?

 

[Shawnna]

Sure does! Thanks so much for your help! I've had my tank up for a year but had a pretty significant crash (self-inflicted unfortunately) about 3 months ago so I really am starting over again. Only now I have that experience under my belt and feel like I'm going about it the right way. I have a new RO/DI unit that I use and am dripping kalk. The pH monitor is my next step on this.

Thanks, again!

milw vs pinpoint

I have a Pinpoint PH monitor and it seems to work fine. I am in the process of buying a Milwaukee PH controller. Everything I've heard indicates Milwaukee's are just as good and the costs are cheaper. Cost is an issue, so I'm going with the Milwaukee. I think they are a newer company trying to grow and erode Pinpoint's market share. Hope that helps.
