Saltwater Pool Tester Free Chlorine Meter pH and Salinity Tester 7 in 1 Free Chlorine pH Salt ORP TDS EC Temp Meter Digital Pool Water Tester pH and Free Chlorine Meter for Pool Hot Tub Spa

It works, easy to read display and reports for me the most important data, salt content and pH.

Does not work - the only test that actually worked was the PH. All other either gave no readings or were. Compared with strip tests and taylor drop test to check. Dont bother. If you want an electronic tester only go pro series and shell a couple $100 to be worth it.

This is easy to use and works great. I sent the same water I tested to the pool supply, and it was almost spot on the measurements. Do make sure you get the PH where it should be prior to testing the chlorine. In other words, just follow the directions that are enclosed.

I would’ve given this five stars, except like many of the other reviews, I don’t get much of a chlorine reading most of the time. The other readings are pretty accurate and the unit is easy to use.

Seems it work, but hard to make it useful, specially all the reading hard to make sense except few. Reading not specify what the value represent except Salt and Ph reading. Never able to get FAC working, always show value 0, tried what I can do based on manual come with. Need help to replace this or return.

Always shows zero or .2 Chlorine. Pool lab tested water at 4.0 Chlorine and 7.2 PH. This unit showed 0 and 6.5ph with same water. I did the recalibration using sample fluids. Still same results after recalibration. I dont have more time to waste trying Chinese poorly made products. INACCURATE, POOR VALUE, DOES NOT WORK.

I read reviews suggesting to calibrate, plus the instructions said so. It was perfectly calibrated out of the box! This works perfect for measuring levels in my hydroponic system, and I even use it to check my pool occasionally. Goodbye test strips!

Very accurate at everything except for chlorine..... it's way off, have recalibrated several times and pH level is nominal....
