## Description

Mimic So Your Fish Can Make It Stress greatly contributes to the health condition of your fish. One of the factors that can cause a feeling of restlessness and tension to your aquarium is a change in their environment as they are in a home away from home. In the case of saltwater tank fish, the water’s salinity level needs to mimic their native home. If the concentration of salt in the aquarium water is not adequate or constant, your fish might fail to thrive. Refractometer by JOR is a helpful dual-range scale device that can assist in maintaining salinity and the specific gravity of your saltwater aquarium or reef tank. Here’s an easy step-by-step guide on how to use this precision instrument: Place a few drops of the sample liquid on the angled prism. On the angled prism, put 2-3 drops of the sample liquid. Use the mini screwdriver to calibrate and check through the eyepiece if the blue line is on zero. Close the clear plate then look through the eyepiece again while holding it under a direct light source. Keep away from looking directly at the light as it may have adverse effects on your eyes. Check the salinity level where you can see the point where the contrast line crosses the scale. Maintain a healthy level between 1.020 and 1.028 S.G (specific gravity) or 35 PPT (part per thousand). After using, wipe with cloth then keep the device in the strong plastic case. No Job is Difficult with the Right Attitude and Proper Tools Maintaining a saltwater tank is easier when you have proper discipline and education to check the basic parameters to make your fish flourish regularly. It is best to also equip yourself with the correct tools that can provide instant and precise measurements. By doing so, you can give excellent care and enjoy the rewards of having a healthy fish tank.

## Features

- 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.

    Aquarium
  

*by R***P on Reviewed in the United States on 21 May 2022*

Need an accurate and easy way to measure the salinity in my new nano salt tank.  This was just what I need and at a fraction of the cost from local pet store.

### ⭐⭐⭐⭐⭐ 







  
  
    How about that, it works!
  

*by E***. on Reviewed in the United States on 15 February 2021*

I bought this one solely because it was cheap. I figured if it didn’t work or was inaccurate I was just out 8 bucks. But I’ve used it a couple of times, and compared it with a friends refractometer and it came up with the same measurements. We’ll see in the long run but for now it works really well! It’s sturdy and comes with everything you need, just follow the instructions and you’ll get really accurate results!

### ⭐⭐⭐⭐⭐ 







  
  
    Verified accuracy
  

*by C***N on Reviewed in the United States on 1 December 2021*

Easy to read and very accurate. Definitely buy again if this one breaks. But it seems to be very durable.
