pH Meter and Salinity Meter Combo for Saltwater Pool 6 in 1 pH Salt SG EC TDS Temp Meter for Reef Aquarium Seawater Tank Koi Fish Pond PPM and pH Water Tester for Hydroponics Nutrients Growing

Worked as expected

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!

Update: Changed to 4 stars for good customer support, fast responses and product warranty. The replacements are working better. Salt water is still off, but not as much, +10%. Not been using it for a while, now Salt water test reports way too high. Pool shop test report showed 3400. This test tool showed 4600-4700 multiple tests on last few days. Ph seems to be ~+2. Not sure on other tests as I am not testing them. Would warranty cover these issues?

Easy product to use, and the screen is nice and big for easy reading. Only thing id change is the size of the prongs for testing. Maybe a lil smaller.

Then I had issues with the salt meter. I had gotten water inside the battery compartment. So I bought a second set of the same meters. They are very easy to read and are accurate. Will definitely buy again for this great price
