Hanna Salinity Tester HI98319

Very good

Very good 👍

Works great and the size is perfect. It’s easy to store and very easy to use.

This item is overpriced and very inaccurate. After calling the manufacturer they concur it is only accurate to 2 ppt. Absolutely useless when you’re trying to measure in fractions like 0.6 can be deadly… Don’t waste your money on this POS! even for a reef tank 2PPT can be detrimental to most SPS. This item is absolutely useless.

My kio pond has started to become problematic after 21 years of fish. I needed to check on my pond salinity and other chemicals. I bought this unit as the old liquid salinity test kits are hard to find and apparently has some harmful chemicals in those kits. This is very easy to use and appears to be very accurate. It comes with a test sample of a known solution to verify the instrument. It has worked well for me.

It’s a must have…A No Brainer….

The level of salinity very close

Tried the standard plastic meter and microbubbles and inconsistencies drove me nuts. Opted for a refractometer and it was ok, but I had to calibrate it before every use and sometimes with my eye site it was a pain to use. I opted for this as it was straight forward calibrating it once and it takes seconds to get an accurate reading. This should be the first choice over the others. It costs a bit more, but you get it back in ease of use and assured accuracy for your tank.
