I had a digital that needed calibration powder to set the pH but I found it could easily be wrong. I bought a calibration solution but the pH is different from the powder that came with it, so it's difficult for me to test and adjust the pen. So I got this one so I can always setup Ph manually with my solution. The disadvantage of this is that it only has one decimal place, in contrast to digital it always has two decimal places. But it reads faster than digital and is easy to use.
