Description:
Rhino Salinity Refractometer ( HR201 ) can be used to measure the salinity of seawater, especially suitable for aquarium and marine applications.
The special Teflon coating on the surface of the refractometer has anti-corrosion propertites and better protects the instrument.
Rhino salinity refractometer is equipped with an automatic temperature compensation function, which can minimize the influence of temperature on accuracy.
which is performed at 50-86°F ( 10-30°C ) instead of 68°F ( 20°C ).
The specific gravity ( D 20/20 ) and a few thousandths replace the poor quality and difficult to read hydrometer.
These are the most common units showing water salinity. With this Salinity Refractometer, you only need one test to get results in two different ways at the same time.
The minimum reading resolution is 1 ‰, which makes it possible to measure low concentration salt solutions. Suitable for aquarium, marine monitoring, agriculture, horticulture and educational purposes.
We especially provide a portable holster for carrying out convenience.
For calibration, distilled water is needed and we provide the water bottle.
Rhino handheld refractometers are particularly easy to use and very sturdy.
