HI 96822  Sea Water Refractometer   HI 96822  Sea Water Refractometer

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.

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).

HI 96822 is supplied with battery and instruction manual.

Range PSU 0 to 50
Range ppt 0 to 150
Range Specific Gravity (20/20) 1.000 to 1.114
Range Temperature 0 to 80°C (32 to 176°F)
