To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I did not realize how important ph is to plants until I got this! I was just assuming that water most likely has a ph around 7 and that was close enough. I bought this little dog and the first thing I learned is that my tap water ph is 8! I went to the store and bought some ph down, added a drop at a time to my water jug and tested. 7 drops in 20oz put me at ph 6.4. My plants reacted immediately! There was new growth evident in 24 hours. I adjust the ph of every drop of water that I use on the plants now and the results are better than anything else I’ve done next to proper light.
Precis pour testez l'eau d'une piscine. Le temps va determiner si ils sont durables et vontinue à se calibrer facilement. Petit bémol, très petit sachet de poudre pour calibrer les appareils. J'aurais payé un peu plus pour avoir des solutions pour au moins 1 saison mais bon on peut trouver en magasin ou sur amazon.
I use these for my aquarium, my reverse osmosis unit, my grow room as well as my outside gardens. These are precise and affordable instruments that anyone doing any of these activities seriously should own.
The TDS meter is very accurate. Make sure you wash it with distilled water every time you use it The Ph meter is very accurate as well and use distilled water as well. Both these meters will break if they are dropped, so be careful.
I used several ph and ppm meter reader and that's the best quality/price item that I've found. I order the red one but it isn't precise as these one (ph) and what about the ppm meter. It seems like the other brand try to copy this one and sell it at higher price. Hahaha. Don't hesitate buy this combo and buy two to make sure you reading is good. ;)
Je n'ai pas trouvé d'utilisation pour le testeur TDS par contre le testeur de pH me sert tous les jours j'ai comparé les résultats avec des bandelettes et les résultats est comparable mais beaucoup plus rapide écologique que les bandelettes
