Would this ph probe be able to be used with brucontrol?
Thinking we could use it for our effluent ph correction if so.
Absolutely. I cannot speak to the accuracy or repeatability you will see, but measuring the output of the sensor is easy enough. The output of the sensor should be wired into an analog input and then the calibration can be performed in BruControl. Please see the schematic for Analog Sensors in http://brucontrol.com/build/schematics/ for specific wiring.

Hello Pete,
Have you come across any other PH monitor probe solution besides the one listed above?
Cheers,
Todd
Atlas Scientific seems to have a nice kit with an analog output. This link gives a look: https://www.homebrewtalk.com/forum/index.php?threads/BruControl-Build-%28completed%29.654550/
for the sake of experimentation and because im always game to test the cheap stuff I bought one of these...
if it works I will by a better quality probe and see how reliable it is.
Good luck - let us know how it goes. I think you should expect general repeatability in the beer brewing range, but dialing-in hundreths of pH will likely not be possible.
Also for ATC, you will need somehow to interface a temp probe.

I've read it reads accurately between 10 and 30 degrees c and goes up about .01 up to 50c... I dont intend to use it at high temps because it dramatically shortens the life of the probes on all ph meters from what Ive read.
I am unclear though on how to calibrat it in brucontrol? I know from these directions how to calibrate the probe to read 2.5 as a ph of 7 but im a bit unclear about the rest so far. https://www.botshop.co.za/how-to-use-a-ph-probe-and-sensor/
this board does also show a temp compensation sensor mounted in the corner.
My fault I thought we where talking about mash ph in process.
I know this thread is old, but I wanted to see if there is any update regarding the performance of a chosen pH meter here. I do kettle sours, and the Lacto can take 24-48 hours to hit target pH. I'm interested in integrating a pH meter into my souring kettle so I don't have to keep popping the lid to take pH readings.
Broadly James has a pH meter with 1/2 NPT, and it is designed to be integrated with an in-line T, so I'm considering a weldless 1/2 NPT bulkhead with that meter attached. I've emailed them about other details and pricing (I can't find that product for sale anywhere; you have to request a quote from them).
The Broadley James meter is here: https://www.broadleyjames.com/product/high-pressure-in-line-ph-sensor-with-integral-housing/
I'm not too experienced with inline pH meters. Perhaps @DieBeerery or another can answer.
Thanks! While I wait to see if they are still poking around here, I assume for an ESP32, these probes, being analog, would use the 3.3v and an ADC1 pinout? (I read ADC2 can't be used if WiFi is enabled on the ESP32s.)
