Chlorine PH Tester Kit Pool Water Tester Electronic Water Quality Analysis Water Test Meter

The reviewers that call it junk because they couldn’t figure out the calibration process are quite obviously lacking in the most basic of comprehension skills. This product works great and is very easy to calibrate. The one star reviewers here deserve one star for their application of intelligence. They are just too lazy to follow the instructions but not too lazy to run their mouths untruthfully about this fine chlorine and ph meter.Skeptical buyers like myself, take heart. This meter works perfectly.

you have to use the traditional color/water test to calibrate.

If I had or wanted to use a "Conventional liquid test kit" i would have bought one! Waste of time and money, just buy the kit and save batteries!

I'm a professional. I carry the reagents necessary to test pool water and calibrate this meter, and I've been CPO certified for over 10 years. I thought I would try this and see if I could save some money on the expensive Taylor stuff.I'm on my my second tester. Neither lasted a month.The pH side of the tester was NEVER near accurate, not once.The Chlorine side was ok... for about 2 weeks. Sand probes before every use and calibrate once per day. Then it stopped. I'm guessing it gets an ORP reading and scientifically guesstimates the free chlorine equivalent. Who knows. It's never been dropped and has never been wet, save for the probes.I gave it 2 stars only because the chlorine side kinda worked. Until it didn't.Spend a little more or a little less on a proper test kit.

Works ok

Does not read chlorine level unless you set it. Seems useless when you don’t know if it’s reading properly

Difficult to calibrate but works well.

Granted, the price was low for something like this but I found this very hard to use and hard to read which meant I couldn't use as I couldn't get accurate readings. Stick to the chems.
