Bests & Worsts Reviews from Amazon

My 150 gallon tank was having fluctuations with ph since my relocation so I needed to easily monitor it. I was amazed at the ease and accuracy of this meter. I have had other ph meters but none were waterproof. It is really nice not having to watch the water depth when inserting this probe. The temperature is extremely accurate being within less than 1 degree of my aquarium thermometer. Great value, superb instrument. You won't be disappointed. I would buy it again
