Hanna Marine Salinity Tester HI98319

Easy to calibrate and use!

Has greatly improved my QT procedure. Now, after I drip acclimate from the QT tank, I can ensure that the water parameters (salinity and temp in this case) are actually matching in the bucket. Makes sure the acclimation period has actually achieved what it is expected to, instead of guessing. Same with mixing salt. Pour in salt, let it mix, wait 20 minutes and test!

Catastrophic product...inacurate compare to two or three other salanity checker...as neptune, milwaukkee and on and on Offset by 2 ppt.... Ot seems that hanna is using another calibration solution...... If you calibrate it with neptune solution...it will resd as neptune is.... If you calibrate it with accurasea it will read as othernthat have been calibrated with it... But when calibrated with hanna liquids...... Ot will then be offset...... Hanna keep saying that their products is THE one that must be followed.... Your choice to decide..... @ Hugo we appreciate your review, we helped you last month and determined the unit was defective and also agreed to send you a new one once we got the bad one back. Im not sure why you would rather review a defective unit rather than getting it replaced under warranty. Your choice to decide I guess

was abit worried that this tester would be inaccurate like my similar PH tester but I am very impressed with it ,quality construction and dead accurate so far!

Very quick easy didn’t even need to calibrate it turn it on and dip it.
