YINMIK pH Meter for Hydroponics, 4 in 1 PPM EC Meter for Plant Nutrients | Simultaneous Measurement of pH Conductivity TDS Temperature, for Reservoir Tank Water, DWC, Aeroponic Garden

This meter worked well and did what it was supposed to do. It provided accurate readings for my hydroponic setup and helped me keep my nutrient levels where they needed to be. I did find it a little confusing to use at first, but that could just be me. Once I figured it out, it performed reliably. Overall, it’s a good tool, just be prepared for a bit of a learning curve in the beginning.

Work as advertised I was new to using this type of device. Good instructions I calibrated the PH with the provided solutions and everything is going well. I use it for hydroponics. Switching back and forth between the settings is very fast and easy.

So far I've only used it for checking pH of water for plants and a swimming pool. I check calibration before every use. The calibration is really stable. I only calibrated when I first used it and it's remained stable ever since. Calibration is pretty straightforward also. I'm really happy with it. I worked in a chemical lab for 20+ years and have worked with a lot of pH meters. This the real deal.

Happy with this. Seems reliable so far. Supplied with enough calibration solutions for several resets. Bought this to replace the Vivosun meter which was rapidly unreliable and almost ruined my crop. It also was only supplied with enough calibration for the initial setup. This product is FAR superior.

Very Accurate, Simple to use. Great tool when you got a RO water filter. TDS, Ph to estimate Alcalinity and Conductivity to estimate Water Hardness (calcium and magnesium ), beside TDS (everithing else disolve in the water. are similar but not the same.

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.

At first, it worked great, but after a few months the stupid thing WOULD NOT CALIBRATE!!!! Despite numerous attempts it wouldn't calibrate.

I am pleased with this pH meter. I use it often to analyze the water that delivers nutrients to my orchid collection. It has brought me to the next level and my plants are better than ever.

Working very good

Works good I like it

very handy. all readings displayed simultaneously.

It works and comes calibrated pretty well. Definitely best one ive had so far

Easy to use
