Can anyone recommend a reliable pH meter under $100.00?

@harsu I have the meter listed here and it has performed AWESOME for the last 18 months. I have only calibrated it once and it is still accurate ! This only runs about $50 and is well worth it in my estimation. If I ever break this one, I will replace it with the same one or a newer model.

pH testing equipment will arrive soon, I need advice as to the best product for adjusting water pH.
There seems to be many choices out there. I am growing in soil and using untreated well water.

My water pH is 7.0 using a cheap two prong tester (which I do not trust).

I use General Hydroponics PH up and down. A pint of each will last a year.

And calibration solutions if you don’t have

And please, store your pen probe in the 7.0 calibration solution, in the cap of the pen, it will last longer and will give you accurate reading 
be advise that you propably will need to change the probe (the interchangeable tip) around each 6 months, but it can last longer when stored adequately… @merlin44 @harsu

Hi Al. The Apera manual tells you: “The probe should be stored in 3M KCL solution for best accuracy or stored without any liquid”. That may be for Apera only, not sure. I personally would not store it in no liquid but I have had great results storing it in the KCL solution. Jerry

This the pair I’ve been using now for a year. Once a month the check mark will disappear telling you it’s time to clean and calibrate. You do store the PH pen in a solution inside the cap. You must leave it hanging to store it properly. You can get the pair for about $135

Jerry, Do you have the combo pH/TDS one @TxGrowman ? However, it’s true that the better is to keep them in 3M KCL solution Thanks my friend to pointed that out

Mine is the Apera pH20 that tests pH only from 0-14 pH. I have a different one for TDS.
