I’m tired of dealing with pH pens/meters that constantly need calibration, don’t last long, or lack precision. The cheaper ones are especially unreliable and hard to maintain.
I’m thinking of creating my own pH tester and would love your feedback! What features would you consider important for a high-quality pH pen? For example, would you value better precision, easy calibration, Bluetooth connectivity, EC readings, or temperature compensation?
Unless you can create a sensor that can do everything, no. I test for chlorine and ph a lot. I employ the drop test for ph and the Taylor FAS-DPD test. Having an electronic pH meter doesn’t save me much time if I still need chemicals to measure chlorine. I might as well test ph using a drop test.
@Terryanne Does “everything” include temperature, chlorine, EC, and orbdity? Does it make a difference whether it fits in your pocket? What about accuracy? Is calibrating a hassle and how frequently do you do it?
@Gia Why do you believe you might perform better? Reliability and accuracy are paramount. Which of your techniques sets you apart from the others? How are you going to fix the issues you brought out, including the need for continual calibration?
@Umbrielle There is a problem with constant calibration. However, I believe that for many, it also involves determining when to calibrate and if it is successful. A knowledge in physics won’t assist there, in my opinion, unless you’re discussing a new probe, which is something I’m thinking about. If I were to choose that path, I would also need to think about the expenses.
