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

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.

Very nice item I really like it. I only wish they would let you know that if you purchase off Amazon, it does not apply to their reward system so if you’re looking to get anything off of their rewards program purchasing through Amazon, just buy from the website I had to learn that the hard way spending over $1500 on AC Infinity equipment off Amazon with nothing to show for it as far as the rewards go.

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

I really like it. Looks like no other meter and it's pretty cool looking. Ac infinity always is top quality. Andease to calibrate

Buyer beware. I had read a few reviews that said theirs came used. Trusting the brand and how much other expensive equipment I own from them I gave it a shot. My ph meter was undeniably used. Dirt on the pen. Batteries showing signs of corrosion. The seal on the 7.0 test fluid has been opened. It saddens me to say to avoid this particular product from them. Clearly QC is non existent for this item.

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.

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

Pen quit working under warranty and as always AC infinity took care of it.

Love it . Instant read is a bonus over the cheaper ones . Highly recommend

Calibration with the provided liquids is required before first time use, mine was 0.8 out which could lead to nutrient lockout if not addressed. Otherwise great bit of kit.

La marca es de lo mejor en todos sus productos. La pega en este medidor es que dura entre 1 y 3 años, dependiendo del uso y el mantenimiento que se le haga. Seguiré fiel a la marca, pero este tester no lo volveré a comprar.

Very user friendly I love it
