Blue Lab for the win imo.
I am not sure that I have seen any meters that don't need to be calibrated periodically? Are there any?
I use the hanna all in one. Tests temp ppm Ph and EC. I buy the 2 part calibration solution by GH for $15 and periodically calibrate for peace of mind. Was the first thing I bought when starting Hydro and was the best $150 I spent.

I have had my tds and ph meter for over 6 years, same probes on both, work as good as new.
. How do you make your own calibrating solution. if I may ask?
Thanks Zem, does it have to be distilled water? I will try it and see where my meter is at.
