This refractometer is a portable, precision optical instrument. It is designed for the measurement of seawater or very low concentrated salt solutions. It measures on two scales - specific gravity and parts per thousand, making you get two readings at the same time in just one test. It is portable and needs no battery, it is easy to learn and use, easier and more accurate than a traditional hydrymeters, it is convenient for all people-children and adults, old and young, ideal for seawater and marine fishkeeping aquarium, saltwater pool,marine monitoring, agricultural, gardening & educational purposes.
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 salinity of general corrosive liquid. (But we do recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. )
The Dual Scales:
The scale range of this refractometer is salinity of 0~100‰ ( 1‰=1 PPT=1000PPM, PPT means"parts per thousand", PPM means"parts per million"), it also shows 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.
Include: 1.A Refractometer + 2.A Firm Box + 3.A Cleaning Cloth + 4.A Screwdriver + 5.A User Manual + 6.Some Pipettes
