Digital Salinity Tester for Salt Water - Waterproof IP67 Salinity Meter with ATC Large Range 0-200ppt Saltwater Tester for Seawater, Aquariums, Marine Monitoring, and Koi Fish Pond by ORAPXI

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.

Works great. Checked it and then a water sample checked at a local pool store and the results were the same.

Works great, shipping was quick

Easy to use and provided peace of mind when the reading on our pump is saying low salt but we know we added plenty.

I ordered this device to test the pH and salt levels in my pool, in addition to using the Taylor Test Kit 2006C. My intention was to use it to verify the instant salt readings from the Hayward T-cell-15 and reduce the need for pH testing with the Taylor kit. However, after numerous attempts to calibrate the pH using the powder included with the device, and even bought the salt solution to calibrate the salt, I found that it consistently gives pH readings that on average are between 0.3-0.5 lower than expected. Additionally, the salt level measurement is about 300 ppm lower than the instant salt reading from the T-cell chlorinator. I am still searching for a reliable device that can accurately measure pH and salt levels in my pool.By the way, I notified the seller, and they issued a refund.

Works great! Easy & convenient. Accurate to read out from pro water eval.

Easy to use and accurate!

Great
