Description

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 distilled or deionized water, 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.

Easy, accurate and precise by JOHN V SIMON Experience Level: Expert Posted on 9/11/2009 from ANNA, TX UNITED STATES Comments: This unit is a great combination of accuracy, precision and ease of use. Calibration is on button push and takes seconds. Reading salinity is just as easy and since the unit give salinity in PSU, PPt or SG there is no need for a reference table. I wish all tests for my reef tank were this quick, simple and straightforward. Yes, I would recommend this product to my friends.
