Buy this item and earn 199.95 points valued at $10.00. 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.
