7-in-1 water meter... that displays only 3 parameters !
After some research on AliExpress & Taobao for some pH & EC meters, I finally found a unit that was quite cheap and provided pH, EC & Temperature reading.
I even found a voucher to get 5% on their "original" website
The unit is quite compact and is delivered with an ORP probe, but as there's only one BNC socket, it is either pH or ORP...
