Product Description

The Hanna Instruments HI 96822 refractometer is a portable meter for measuring salinity levels in natural and artificial waters.

The refractometer measures the refractive index of water samples in order to display salt content, with results available within seconds. To take a reading, the sample well must be calibrated with distilled or deionized water, followed by a few drops of the sample liquid. A dual-level LCD screen displays the measurement and temperature within several seconds. The HI 96822 converts the refractive index of the sample to one of three popular units for measuring salinity: Practical Salinity Units (PSU), Salinity in parts per thousand (ppt), or Specific Gravity (S.G. [20/20]).

The 9V battery-operated device utilizes a yellow LED as a light source, and automatically powers off after three minutes of non-use. The HI 96822 has a range of 0 to 50 PSU, 0 to 150 ppt, or 1.000 to 1.114 specific gravity and automatic temperature compensation between 10 and 40 degrees C (50 to 104 degrees F).

Refractometers measure refractive index, which is the optical characteristic of a substance and the number of dissolved particles. Refractive index is the ratio of the speed of light in empty space to the speed of light in the substance. Refractometers are used to ensure proper salinity levels in natural and artificial waters.

Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents, and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To assure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.

I have a fish only tank with live rock, and I upgraded from those junky float meters for salinity, to a 40 dollar refractometer. A couple months went buy and everything was measuring well, but then started getting calibration problems, and the test results would vary slightly. Measurements should be on the money I would imagine, but I Could not get them anymore.
I got mad and upset so I bought the HANNA SALINITY checker. Big waste of time and money.
I got the unit, and the next morning I did a bunch of different tests on the unit. Followed the instructions exactly, time and time again, I even tried varying the way I tested. I zeroed out the unit, used different test samples, used the same test samples, all brand new, rinsed out syringes, used distilled water, rinsed out the test well on the unit, and even used certified testing fluid.

After over a half hour of testing all these variables, in multiple ways, you would think that I would have at least one test reading that was the same???
All test results were different, and I don't mean by just one number. I got readings of 24 ppt, to 30, to 31, to 32, 33, 35, 40,41 and so on.....

Not impressed at all. Promptly packaged, and returned this unit to amazon.

A have 2 apex Jr. Running multiple probes, a huge battery backup setup using 4 deep cycle batteries, aqua illumination led units, 6 foot long tank in my basement, running through the wall into my Sump room.

And I still not have found a device that can measure the salt in my system properly, and consistently. Lol lol.

Do not buy this unit. I give it 0 stars, not 1 star.

This refractometer is easy to use. Readings and calibrations are very quick. My only complaint is the rubber feet on the bottom. There are about six of them, and I lost one on the first day I got it. It fell off somewhere. It would be nice if it came with a plastic carrying case. For now, a tupperware container will do.

Large enough to see the results quickly. Simple to use. I am disappointed they did not include a storage case with the purchase. I double checked the values with my manual salt reader and the Hanna Refractometer worked well.

much easier than a refractometer. Nice large display. No reagent needed. Just zero with distilled water each time. Just the cost of two high end Frags.
