Buena calidad

Thanks..fail safe meterVery very useful to me..I measure my plants food strength with this meter

Tests water for hydroponic EC measurements very well. No need to spend $100. Price point for something like this is perfect, it’s not junky but isn’t extra plastic just to charge more. Accurate and plants are thriving because of it. Thank you for no gouging.

I bought this for making beer and winebut decided to try testing our tap water. I don't have calibration standards so I can't speak to accuracy, but the results seem in line with our water supplier's testing. As long as the results are repeatable, I'm getting what I need from it

The device works well. It was successfully cross-checked with another calibrated device from a different manufacturer.

I use this meter several times, each day, as I own a fish room and have many tanks that need attention. It seems to be working great, in every possible way. I love it.

Used for 1 month. I ordered this to check my distilled water quality that i order from the water company and it shows 0. Tap water 240. After reading a lot of reviews I settled on this product and it has been perfect! I also use test strips that show no harmful additives in my distilled or tap water.

Able to determine the salt level in my swimming pool easily and quickly
