AC Infinity pH Meter Kit, High Precision Digital pH Pen with ±0.1 pH Accuracy, Nutrient Test pH Meter for Water Hydroponics Plants, Gardening, Aquariums, Swimming Pools

Works great, stabilizes very quickly and accurately. It's the first pen we've used that recommended storing in the solution and i think that absolutely makes a difference. Have tried a few brands, both cheap and expensive ( blue lab, apria, a couple other i don't remember) and this is definitely the best

AC infinity is always on point with heir merchandise,this ac infinity ph pen accuracy is on point it’s functionality & is very easy to use all ac infinity products are built with quality & it worth the value of its money it’s sleek appearance is like no other

It's an amazing product really easy to use very accurate it's really functional pretty easy to clean and it's a very good value for its money

Decent ph meter: have to regularly calibrate but seems to be working pretty good. Easy to use and calibrate and comes with a hard shell case to store it in. Middle of the road price range in between the best ph meters and the cheapest. Price was decent for the quality of the product.

Solid. Been using it every day for a good month and has kept calibration the entire time. Durable enough as I may or may not have dropped it once or twice and someone left it in the green house cooking a couple times. Not me of course. Lol

Inconsistent readings does not work

Quick and easy reading

I had multiple cheap ph meters and decided with the amount of money I spend on everything else for hydroponics I should get something a little more accurate. One of my other ph meters was off a half point and the other was fairly close. This seems to be a far more solid piece of equipment and so far it seems to be worth the extra price for a little added accuracy.
