Pool Salt Tester ORAPXI pH and Salt Meter for Saltwater Pool pH and Salinity Digital Tester 5 in 1 Salt Meter for Swimming Pools Hot Tubs and Swim Spas

The tester was very easy to use, and very accurate. I compared the salt readings I got with the tester with the salt test at my local pool shop and they were the same. It's a good unit, accurate, and very easy to use. I'd recommend it for anyone that has a salt water pool or any pool.

I changed from a Hayward T3 salt cell to a generic brand. The new salt cell works fine but it would not calibrate to the actual salt readings. I bought this to use and found it matched my pool stores reading exactly. Very easy to use. I dry it off before I put the cap on and put it away.

It is easy to use out of the box. It is very consistent with the salt level readings (I double-checked with a chemical tester and the difference was less than 100ppm, which is fine to check salt levels for a pool with a salt chlorinator). So worth to do salt level measuring - takes a few seconds and reliable. As for pH, you have to calibrate it frequently (it comes with the powder to do the calibrations), but becomes a hassle to calibrate and you never know if it is calibrate it or not. So I use the chemicals to measure pH (just more reliable and consistent over time).

Bought this for our saltwater pool. Worked great right out of the box. Haven't calibrated the pH sensor yet, but it lines up with readings from our chemical test kit. It will pay for itself in the cost of salt test strips alone.

In December, I received nice salt aquarium for Christmas will all the bells and whistles. However, while bringing it up, i didn't like using the traditional refractometer as it can be hard to see. So I bought this. Everything worked fine for 45 days. Then I performed a water change with water I had made to match the tank. I did the change. Later that night, I use the meter to spot check the tank as that is what you do when you micro manage your marine tank. It read 28ppt. I panicked and began raising the salinity over the next day to 35ppt. All is fine. I thought! Then 95% of my large inverts die. All snails but one, all shrimp but one, all crabs but one, and all copepods. I cannot figure it out, checking everything. Next, my coral. All but 4 frags die. 2 of those very ill. I run an ICP test my water comes back perfect with the exception I'm at 44ppt. I assume something could be wrong on their end and took my tester to my son's house and put them side by side. His read 35ppt in his tank, and mine reads 27.5. Never trust this when you have animals lives at stake. If something seems off get the refractometer out. This device and my trust cost me about $500 bucks in livestock.

This device is great for checking the salt level in our pool!

This tool is easy to use and great to get quick readings to maintain pools.

It only lasted a year and then the readings were inconsistent and they were taking a long time. The readings seem to still change after more than a minute in the water.It was great while it worked, but I am not sure how accurate it was, and I expected to last longer than a year after cleaning it every time in distilled water and keeping it in a box inside the air conditioned house,
