Effectively monitor the salt value of your aquarium or tank by refractive index measurements using the Hanna Instruments Digital Seawater Refractometer from Pet Store
. What makes this refractometer convenient to use it its being ruggedly portable. You can easily carry it around and just use it whenever it is needed. Aside from that, it will not easily get wet or be immediately damaged when wet. Moreover, the device performs well in its function to determine the salinity in brackish or ocean water
intermediates. Though, it can also be used for artificial and natural seawater.
Going further, the Hanna Instruments Digital Seawater Refractometer is a product to be trusted as both the device and the manufacturer have a solid reputation. Using this refractometer, you can surely get accurate results that will be converted to either of these popular measurement units - specific gravity, salinity in the water parts per thousand, and practical salinity units. Even better than that, you only have to do a simple calibration with deionized water or distilled water and introduce a sample in it. So, it is not only reliable, but simple to operate.
With all these desirable features mentioned, this digital instrument will not disappoint you and is probably better than the mechanical ones. 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.
