HQRP 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 (‰). With just a couple of drops of aquarium water you know exactly what your salinity is. Vital if you need to check salt levels when preparing sea food and other ocean by-products.

Mesurement range:
Salinity: 0 - 100 ppt (0 - 10 %), Minimum Division: 1ppt (0.1%);
Specific gravity: 1.000 to 1.070 g/cm3, Minimum Division:  0.001 g/cm3.
