JOR Refractometer, Dual-Range Scale Device to Measure Salinity and Specific Gravity of Saltwater Aquarium and Reef Tank…
Dual-Range Scale Refractometer --- A healthy saltwater aquarium requires a salinity balance or the salt concentration in aquarium water. Refractometer by JOR helps maintain this fundamental parameter in your saltwater aquarium or reef tank, measuring both salt percentage and specific gravity. This measuring tool has a scale range of 0 to 100%, where 1% means one part per thousand (PPT) or 1000 parts per million (PPM) and with a corresponding specific gravity range of 1.000 to 1.070.
Provides Accurate Measurement Reading --- Forget guessing and estimating. This handy refractometer features automatic temperature compensation that gives precise, faster and easier readings.
Easy To Use --- Place 2 to 3 drops of aquarium water on the glass, then close the plastic cover. Look through the eyepiece as you hold it under a light source. Check the reading. The blue line indicates the exact salinity level.
