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...
And we can't count °F & °C as different features.
