Dosatrons with inline ph meter?!

[Hash Man]

Anyone know how to install a ph meter inline with a fertigation system? The only thing I can come up with presents a few problems. I'm planning on using PVC glue to glue my meter into a 1/2" T, and putting that after the dosatrons. Any suggestions on an adaptor or something? My meter will need calibrating and could be damaged by the heat. Any less permanent options?

how is it set up do you have 2 injectors one with nutrient brine and one with ph up/down

3 injectors. I do everything I can to stay away from ph up and down. I use lots of different stuff and keep the ph in check by using a strong feeding of potassium silicate in the first injector. most of my nutes lower ph, so over the years I have learned how to play my low ph nutes off of my silica. I want to put the meter after all 3 dosers.

you shouldnt need to have a meter after them just a hose bib to check the ph before each use if its off you need to adjust the injector ratio manually anyway

I have the hose setup. I want the inline meter so I can see the real time info. Dosers are awesome, but when they fail during a feeding, it can adjust your ph without you knowing. When it happens it can be catastrophic. I don't want to keep walking up my hill during watering to double check the ph and ppm to make sure it's keeping the same strength from beginning to end. I know a couple guys around here are doing it and hope there is a way to do it without having to waste lots of ph probes this year.

Ok I figured it out guys. I took the threaded piece off my ph meter and tried to fit it into a 3/4" coupler. It didn't fit. So I dremmeled it out and used PVC glue to fit it snug in place. Then I put the 3/4 " coupler into a 1" T. I have lots of spare meters from over the years so I have 8 or 9 of these little threaded pieces that hold the probe to the meter. I'm on my iPhone so I can't post pics now but this is going to be a game changer for me, so if my explanation doesn't make sense, let me know. I'm using a regular handheld ph/ppm meter from eu tech instruments. I'm going to put in 2 check valves before and after my new custom threaded t so I can stop the pressure flow and take the meter out once I'm done.

Actually it didn't turn out so well. I'm going to grab an industrial meter and probe that is built to go right into a 3/4" threaded PVC. The current setup will not keep the inside if the meter water tight when trying to remove it. I like avengers post and would do that if i still had my blue trimeter.
