      Great price for what your getting.

      While I like this meter a lot, there are some issues I don't care for. The nice feature is the calibration of the meter, very simple and quick. It is great that it comes with its own 7.0pH and 4.0ph calibration fluid. One less thing I have to buy to get a meter to work. The only gripe I have is the main button (and this could be user error) the meter will go into a region of use and I have a hard time getting it back to the main menu. Otherwise a great tool.

      Excellent choice on a budget

      For the money you can't go wrong. I wish I would have bought this 1st. This is replacing a slightly cheaper ph meter that came with none of the accessories this meter did. The instructions on use, storage and calibration are excellent. It also includes a case. Do yourself a favor and purchase some kci fluid for storage and this may be the last ph meter you buy.

      it holds calibration.

      Easy to use and understand, does not have to calibrate as often as other pens.

      Had less than a a week and already needed to be recalibrated

      This seems like a pretty nice quality meter, and a good value, and it also comes in a nice carrying case. I have had a number of cheaper meters in the past but they never lasted very long. The cap for the probes often are not well sealed on cheaper meters allowing them to dry out and die. This meter has a nice cap with an O-ring that does not leak, so I expected it to last a while. However I have had mine less than a week and had to calibrate it twice. I performed the initial two point calibration with the included 4 and 7 solution, and then 5 days later I noticed my readings seemed a little off, and moved around a little. I checked the calibration with the pH 7 solution and got a reading of 7.2, so I recalibrated and it seems to be reading accurately. That was yesterday so I will update my review after I get a chance to see if it continues to take consistent readings.

      Too pricey

      What I'm saying is too pricey, is that for what this thing does and how it works, it's too much for what you get. Clipped it on the side of my hydroponic nutrient mixing pitcher, clip failed and dropped in the water and ended up frying it! Now it's stuck in Cal0 unless I hold the buttons down in which case it jumps back between pH 7 and pH 4 calibration modes. The seal around the solution storage cap (where you store the diode) doesn't seal properly, so if you put it back in its storage case, make sure the case doesn't lay on its side or anything, otherwise all the liquid will leak out. However it was easy to read and easy to use, just a pain that of what I went through.

      Apera

      When the smiley face comes on the readings are still rising and lowering. I thought once it came on it was a correct reading and would lock that in.

      Well made,and most accurate

      Apera, you just can't get any better, it's accurate every time, and calibration is easy.

      Nice ph meter and a nice case.

      A little bit difficult to calibrate. But once you get it done has been perfectly calibrated since. Been a week and still doing great.
