Salinity Refractometer for Aquarium Seawater Marine Fishkeeping Dual Scale 0-100 PPT& 1.000-1.070 with ATC
This refractometer is used to test the concentration of brine and help you monitor and control the concentration of brine. Widely used, can be used for aquarium, ocean monitoring, agriculture, gardening and education purposes.
This refractometer is designed for measuring the salt content and specific gravity of liquids, a refractometer includes both salt percent and specific gravity scale. You won't have to do conversions between salinity and gravity when doing measuring, you'll get the two index in one time.
Dual Scale
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. ( 1‰=1 PPT=1000PPM, PPT means"parts per thousand", PPM means"parts per million")
High Quality
Seawater refractometers with premium optics and smooth focusing. The internal optical lens with high refractive index ensure the precision optical system so we can get the accuracy measured results and view the scale clearly.
Easy To Use
Refractometer is based on the principle that the refractive index of liquid changes with the concentration. It is portable, simple, fast, does not need batteries, is easier and more accurate than traditional hydrometers, and is more affordable than digital meters.

Product Features
ATC Function
Saltwater refractometer with ATC function can automatic compensate for changes in ambient temperature, making the reading more accurate.
Clearly Eyepiece and Scale
This salinity meter features clearly lens and smooth adjustable focus, easy to read the clearly readings by manipulating the eyepiece.
Adjustable Visual
The eyepiece can be rotated to adjust the definition, so that you can read the readings better.

Wide Application
For Aquariums Water Monitoring
Perfect for aquariums or marine fishkeeping amateurs, cause they can make the salinity of water similar to the sea water and easy to monitoring daily.
For Marine Research and Monitoring
Most sea water's salinity is about 30‰~35‰. So this Brine refractometer is ideal for simple marine monitoring, marine aquaculture and research.
For Fish Tank saltwater Measuring
Use this salinity refractometer to test the salt water of your fish tank at home. It also can be used to measure concentration of brine solution at food preparation.
For Lab Education or Industry Purposes
Ideal for lab use, lab educational tool in shoocl and industry use for testing salinity solution in the range of 0~100‰
.
ATTENTION AND MAINTENANCE
- 1.Adjustment for the null liquid and specimen should be in the same temperature. Once the temperature move greatly, the null point should be adjusted once per 30 minutes.
- 2.After usage, do not use water to wash the instrument, so as to avoid water entering the inside of the instrument.
- 3.This is a precision optical instrument. Handle it gently and take good care of it. Do not touch or scratch the optical surface. Please keep it in a dry, clean and non-corrosiveness environment, to prevent the surface from turning moldy and foggy. Please avoid strong shock during transportation.
- 4.If the consumers use the instrument in accordance with the mentioned method of usage, the optical performance should not be changed.
