Product Details

The HI 96822 Digital Refractometer is a rugged portable, water resistant device that utilizes the measurement of refractive index to determine the salinity of natural and artificial seawater, ocean water or brackish intermediates. The HI 96822 device benefits from Hanna’s years of experience as a manufacturer of analytical instruments. The digital refractometer eliminates the uncertainty associated with mechanical refractometers and is easily potable for ship, shore or home use. The HI 96822 refractometer is an optical device that is simple and quick to use. After a simple user calibration with distilled or deionized water, a seawater sample is in introduced to 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). The temperature (in °C or °F) is also displayed on the large dual level display along with helpful message codes.
Key features include:
• IP65 waterproof protection
• Automatic Temperature Compensation (ATC)
• Battery operation with Low Power indicator (BEPS)
• Automatically turns off after 3 minutes of non-use
