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

Good

Seems accurate and easy to use. I only need salt and PH and it seems to match the pool test strips.

Works great. I will update review for longevity but I suggest getting a glass and put an inch of clean water in it. Keep the sensor immersed in clean water when not in use. The automatic pool controllers sensors look a lot like these and if they dry out they oxidize and lose their minds within days. If you do feel like it has lost accuracy the way to clean the automatic ones is a clean toothbrush and clean water... try same procedure. Like I said, I will update over time but so far it saves do much time just getting an instant read.

I bought this device primarily to calibrate the chlorine generator on my salt water pool. It certainly was easy to set up and use. Just follow the directions at first, going ahead with the calibration process. Then rinse the tip with DISTILLED WATER after each us, allow it to dry, an replace the protective cap. Don't touch the contacts or glass bulb on the tip of the device and don't drop it. If you are careful with it, I imagine this will last a very long time. It seems quite accurate, including taking salinity, pH, and temperature readings. I'm not sure how safe it would be for something that is critical like a salt water fish tank, but for a salt water swimming pool, this device is super, at least so far!

Make sure you have some distilled water handy 1st to complete the PH calibration. It recomends 3 x 250ml cups of distilled water. In each cup you will add the PH solutions that are provided in the box. A base, netural and acidic. Once calibrated it works a treat.
