For a cheaper meter this one is great, been using every day for about 4 months and it’s still doing great and it’s got replacement probes you can purchase so you don’t need to replace the whole thing when you’re probes crap out. Oh and you get all your calibration fluids as well. Happy growing…

AMAZING. After wasting money on other cheaper ph meters and returning some over a years time; this one simply works. Just had bought another from Amazon this time of the yellow/black and it didn't come calibrated, wouldn't hold calibration etc. This item simply worked and right on the mark in calibration fluid, rock steady in usage too. I THINK IS THE ONE YOU WANT, CUZ'SHOULD HAVE STARTED HERE TOO!!

The ph buffer packs are impossible to quickly mix with water. Rock hard in the box.

Seems to be in working order. Even comes with a solution to calibrate the PPMs. Very nice and easy to use. I realized my old PPM meter was WAY off. Quality/build seems to be ok. Curious how long the batteries last with daily use. Very easy to read. I only have to use one meter to test the pH and PPM. It even includes temp, which isnt as important to me because I let my water sit in room temperature 12 hours ahead of time. Pretty good deal for the price. I just hope it's easy to get a new probe when it's time. Will update if anything craps out.

A great meter for hydroponics. Not expensive, reads ph,PPM,EC & temp accurately. Holds calibration through out one grow without having to recalibrate. I'd buy this again.

I use this meter biweekly to monitor my hydroponics system. The meter is quick and reliable so far, and its been 3 weeks. For calibrating pH there are two small bottles of pH 4 and 7 buffer solution, but the pH 10.1 comes in a packet that you need to mix with distilled water (i used tap haha). There is no bottle to store it in so you have find your own - kind of wish this was just provided in a bottle. The EC calibration solution is also provided. the pamphlet gives great instructions on cleaning, storage, use, and calibration. Overall I give it 4.5 (not an option), but only due to the 10.2 buffer solution not being available. Really coming in handy.If you are looking for a smaller probe, find one that only measures pH. The size works well for me so it was not a factor in my decision.

Meter sucks! You got to calibrate every time you use it!

This is probably a good meter, but for me it stayed stuck on 14 pH for RO water which is not correct. I wrote the company, but they did not return my e-mail within 24 hours as promised. I'm the type that needs a video to show me how to calibrate since I've never done this before. Yes, there is a sheet of instructions with pictures, but I don't feel confident in what to do. I need a video, but there is none and no customer support. For those that have done this before, they would probably say it needs calibration or a new battery, but it's brand new and those should be working.
