Feature:
- This dual scale salinity refractometer is used to measure， monitor and control the concentration of salt water and brine， especially useful for aquarium and marine applications.
- This high quality refractometer measures on 2 scales， specific gravity (D 20/20) and parts per thousand and replaces your poor quality and difficult to read hydrometer.
- With just a couple of drops of aquarium water you know exactly what your salinity is.
- This refractometer does not need calibration solutions like some other refractometers. Simply use 'everyday drinking water' to calibrate in 30 seconds upon first receiving or after a long dormant period.
- A refractometer is easier and more accurate than a hydrometer for measuring sugars.
- Made of sturdy aluminum.
