Hanna Salinity Tester HI98319

  • Includes 4x of the Salinity Calibration Fluid Packets..
  • Automatic Calibration – A 35.00 ppt solution is used for calibration and automatically recognized when in calibration mode..
  • Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.).
  • Salinity readings are performed by an amperometric graphite probe that resists oxidation, providing better repeatability in measurements. The use of graphite also reduces the polarization effect common with testers that use two stainless steel pins..

JOR Refractometer, Dual-Range Scale Device to Measure Salinity and Specific Gravity of Saltwater Aquarium and Reef Tank, Provides Accurate Reading, No Batteries Required, 1 Set per Piece

  • 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 c....
