very tidy ,what ph probe are you using ?
This the one im using just for monitoring purposes
PH Meter LED Water Quality Tester Monitor Water Quality Analysis Device ATC S7W6 https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/352521853446
You will see it has the bnc connection so if probe goes bad you can always get a better probe and use it with the monitor
