Digital PH Meter, Water Quality Tester 0.01 PH High Accuracy and 0-14 PH Measurement Range, Ideal Water Test Meter for Household Drinking Water, Aquariums, ATC

Apparently I didn't read the reviews before ordering. After reading the (somewhat confusing) instructions I calibrated the unit and began testing along with API chemical tests. I tested five tanks. "Calibrated" results were so far off from the chemical results! Total waste of money, very disappointing.

Nope. Don’t buy it. The calibration was impossible.

The first time I took the top battery cap off, it would not click back into place, resulting in a totally bricked ph meter. Bad build quality. Also the calibration solutions werent disolving in the distilled water at 21 degrees c and I was having issues calibrating. That part could be in me but no the cap quality.

I got the product fast which was good. But I have a lil problem. I tried calculating 3 times and it still would'nt get right. I thought about sending it back but realized it was just too much trouble. So I chunked it in the trash. I Do not recommend this product at all. It just wasted my time and money.

It works great.

Good quality meter with accurate results

I may have turned this on 10 times, but today it will not turn on.This is by far the lowest quality PH meter I have purchased on amazon.

Took the item out of its case and it didn't even turn on!
