Does anyone know if its possible to buy a meter that reads dissolved oxygen and PH. I can only seem to find one that does either or. Many thanks

I think you can get the desk to maters that do both but they are very expensive and not portable.
I used a Hanna ph meter and separate DO meter

The AJS kit does DO and ph

Yes you can I use them at work, extremely expensive and pH probes need replacing every 6 months to remain accurate as eventually offsets become to great giving unreliable results. AJS isn't a bad shout tbh 👍
