pH Meter for Hydroponics PPM EC Meter for Plant Nutrients Simultaneous Measurement of pH Conductivity TDS Temperature for Reservoir Tank Water DWC Aeroponic Garden Indoor Outdoor Growing

Excellent meter. Read the directions though and follow them! My hydroponically grown plants have really benefited from regular use of meter.

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.

This PH/EC meter has been a great tool for my water PH in my plant growing experience. I purchased this along with the 7.00 4.00 10.01 and the storage solution package. Using both of these products has helped improve my plant growth by accurately giving PH and PPM/EC readings. If you do not use the PH meter a lot, I do recommend calibrating the meter before using each time. So far this meter along with the solution pack has been an amazing tool for my plants.

Instruction manual isn't the easiest to follow but once you get the hang of it, it works pretty good!

The meter is easy to use and calibrate, comes with all the calibration liquids. The tip of the meter has a little foam block to keep your probe moist. So far it has held true to readings which makes it a decent deal considering it does the same thing my Hanna does and faster.

Worked for a little less than 3 months. PH read at .8 way lower than usual. Used PH drops and readings were around 5. Tried to calibrate to no avail. Tried to troubleshoot but couldn’t get the thing to work. A probe costs $20. For around $10 dollars you can get a whole new one. Not worth it. Buying a different brand.

This is by far the best Pen to use for PPM and EC and it’s easy to calibrate and it brings everything with it. I’ve used a lot of pens, and this one is my favorite. I would say even over the trunchun pen . Great value for the money. Very accurate.

I got my Aerogarden water messed up by using too much feeder and leaves started turning brown. I wanted to check the pH and electrolyte levels to see if it was repairable. The problem is I couldn't find anything about what the levels should be. All the articles are for much bigger hydroponic gardens. I finally just changed the water and started over with the feeding schedule. This meter is pretty easy to use and comes with calibration fluids so accuracy can be checked. It is easy to read and change settings between pH and electrolytes. It seems like good quality and gives a fast reading. I'm going to set up a Kratky system next and will use the meter more often.
