Hydroponics EC pH Tester, Simultaneous Display pH ppm for Base Reservoir Water, Continuous Monitoring of pH Conductivity Temp. ppm for Growing Nutrients, Indoor DWC System, Aeroponic Garden

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.

The media could not be loaded. I bought this meter to measure the water I give to my plants in soil and semi-hydro. If you calibrate it correctly, it is fairly accurate. I only need it to measure water that is slightly on the acidic side (below 7.0). The instructions clearly state that if you're measuring acidic water, you should only calibrate using the 7.00 and 4.00 solutions, which I did. I put a video up here where I show the meter measuring water and how accurate it is. It's not perfect, but it's also not very expensive, so keep that in mind.

Used it for about a month and is working flawlessly everyday! Keep in storage solution!

Simple to use pH meter; seems accurate but I have no other device to compare it to. Comes with what you need. Easy to see display. Suits my needs.

I use this to test my water for my garden, it's always seemed accurate. Always calibrated just fine. Comes with more than enough of the liquids it includes. It is easy to read and use. Screen is bright enough but could be brighter. Works exact as I need it to

This is the best ec slash ph monitor I've ever bought the other one I owned was crap, this is a very nice one give it a try you'll be happy and you did for the prize.

Got 3 months out of it. Didn't mistreat it, just stopped reading ph which caused me to ruin 5 gallons of water. Glad it didn't wreck the grow I'm almost at the finish line.

So far so good...fast and accurate. Definitely a steal at this price.
