I was gifted one of these Hanna meters (Hanna Groline HI9814) and it does pH, ORP reading + temp.

It's a more expensive model but seems to do the trick for measurements.

Though I should get some more calibration solution and make sure its still in check. 🤔

If you could use the HM Digital model I have, let me know.
