There isn't really a <"good cheap, accurate pH meter">. They are quite complicated bits of kit, and you need one with two point buffering etc.I have Jbl dropkit but Think its hard to reed sometimes, is there a better way. As a good ph and kh pen or some like it. Nothing with just guessing or malfunction after 5 readings.
Has anyone used this PH-80 – HM Digital ? Any good?
It is not ideal, two point calibration would be much better. If I had ~£50 I would spend it on a a conductivity meter, rather than a pH meter.One-touch automatic digital calibration
............................
Factory Calibrated: The PH-80 meter is factory calibration to pH 7.0.
Includes a translucent cap, batteries, storage solution and pH 7.0 buffer (powder)
Could you please elaborate on this in more detail?If I had ~£50 I would spend it on a a conductivity meter, rather than a pH meter.
No, you can't unfortunately.Specifically how to build Ph profile while dissolving CO2 and using EC meter?
This all makes sense now. My fish tank water has 18GH and 9KH which sounds good re using PH meter and accuracy of measurements.No, you can't unfortunately.
The issue for me is that I wouldn't trust that meter to give you an accurate pH profile. I'm not a CO2 user, so I don't have practical experience of constructing a pH profile during CO2 addition. If you have hard water? you are more likely to get an accurate pH measurement, because it is easier to measure pH in high ionic strength solutions.
The drop checker is fairly accurate, but you have issues with the lag while the CO2 diffuses into the 4dKH and bromothymol blue pH indicator.
