Hanna Instruments Designed for Research Grade Analysis

HANNA‘s HI 96822 Digital Refractometer is a rugged portable, water resistant device that utilizes the measurement of the refractive index to determine the salinity of natural and artificial seawater, ocean water or brackish intermediates. The HI 96822 benefits from HANNA‘s years of experience as a manufacturer of analytical instruments. This digital refractometer eliminates the uncertainty associated with mechanical refractometers and is rugged and portable enough to be used at home, in the lab and out in the field.

The HI 96822 is an optical device that is quick and easy to use. After a simple user calibration with steam-distilled water (do not use RO or RO/DI water for calibration), a seawater sample can be introduced into the sample well.

Within seconds, the refractive index and temperature are measured and converted into one of 3 popular measurement units: Practical Salinity Units (PSU), Salinity in parts per thousand (ppt), or Specific Gravity (S.G. (20/20)). All conversion algorithms are based upon respected scientific publications using the physical properties of seawater (not sodium chloride).

Temperature (in °C or °F) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes.

Manufacturer Info

Hanna Instruments USA Aquarium Supplies
Hanna Instruments is a leading manufacturer of analytical aquarium instrumentation. They were founded in 1978 and are headquartered in Woonsocket, Rhode Island. When Hanna introduced pH Electronic Paper in 1986 it literally revolutionized the world of testing by allowing millions of people in various industries to test for pH in a simple, accurate and affordable way. Hanna employees are constantly challenging themselves to improve on existing technology and to invent new testing techniques with the common goal to simplify analytical testing. This applies not only to instrumentation, but also to sensors development, reagents and chemicals. Hanna also believes in controlling the quality of their products from inception to delivery so they manufacture everything themselves, from meters and electrodes to chemical reagents and buffer solutions.

Little large, nut not a deal kill.
REVIEW
I received the unit last week. Packaged very nicely, and safely. When I first used it after an almost nothing calibration, it quickly gave me the 3 reading from the same sample by simply pressing a button. Accuracy is spot on. I checked using different brand tests to see, but this one is so simple! ...Read More

REVIEW
I started with a hydrometer and then moved up to a refractometer, but I was still uncertain about whether I was reading the scale correctly since the line between white and blue was somewhat of a gradient. After my first week with this digital refractometer, I am 100% pleased. I tested it against t...Read More

REVIEW
Good - it gives the same reading every time. Consistent... Bad - it has accuracy of +|-.003. It read 1.021 on my reef aquarium which was really 1.024. I contacted Hanna and they informed me that it is within margin of error. Well .003 matters in a sps tank.
