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

But we got it to test pH and chlorine, and it does its job well. It gives the same reading as the little disposable strips. This should last longer than 2 or 3 tubes of the test strips, which by that point it will have paid for itself.

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!

I purchased this digital device in hopes that it's quick and easy and permanent. What i get in a box is a digital device that requires special liquids that need to be purchased to calibrate thia device. Soo... Should i calibrate device? Then I should Calibrate to another liquid, and another liquid, and then I should dance.... Maybe i should jump and clap my hands? What other 1000 instructions does this device need me to follow. I hate this seller and I hate this complexity.

Fácil de usar

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.

Have used this for a couple months now. Only measurements that seem to work are pH and salt...and use them to get an idea, not for precision measurements. Free chlorine doesn't work no matter what. Ppm and salt give about the same reading all the time which is suspicious. The other functions I haven't checked because I lost confidence in this device.

Ph and Salt level works good. FC cannot get working

I bought this for my saltwater fish tank to keep track of the salinity. I exchange 10% of the water from my tank each week and this meter gives me a very accurate reading. I appreciate how easy it is to read it and also to clean it after being in the water. I really do have a feeling this meter is going to last me a while!
