  • 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.
  • High Quality And Economical --- This premium quality handheld refractometer has an aluminum alloy body, rubber grip, and adjustable focus. It doesn’t corrode, and since it is analog, it can also save you money because it doesn’t need batteries to operate, sparing you from buying replacements.
  • Complete Care Set --- This portable measuring device comes with a hard case for proper storage. It also comes with a cloth so you can wipe the prism plate. The kit also includes essential tools during calibration and testing, such as a suction tube, screwdriver and a user’s manual.
