aichose is a professional brand of supplying various kinds of liquids measuring instruments.
The refractometer series are based on the principle that the refractive indices of liquids change when the concentration change. It's portable, easy, quick and no battery required, easier and more accurate than a traditional hydrymeters, more affordable than a digital meter. It's a perfect tool for adult or young, home or professional use.
It features high-quality optics with smooth focusing. Its main body is made of aluminum alloy. The internal optical lens with high refractive index make up the precision optical system.The instrument is resistant to abrasion and corrosion, can be used to measure the general corrosive liquid. (But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. )
-
For saltwater aquariums , fish-keeping, marine monitoring, salty pools and other marine applications.
The scale range of this refractometer is 0~100‰ and the corresponding specific gravity range 1.000 to 1.070. These are the most common units to show salinity of water.
With this refractometer you can get the result in two different ways at the same time in just one test.
The min reading resolution is 1 ‰, this make it possible to mearsure low concentrated salt solutions.
( 1‰=1 PPT=1000PPM, PPT means"parts per thousand", PPM means"parts per million")

1Calibration: Place a few drops of distilled water on the prism and use the screwdriver to adjust the calibration screw untill the reading is"0". |
2After calibration, place a few drops of solution you want to test on the prism. |
3Close the daylight plate and hold it under a light source, then look through the eyepiece, you can get the reading. |
4Clean the instrument with a soft cloth after use, and put it into the storage case. |
