1. Professional Automatic Temperature Compensation Salinity Refractometer for Aquariums, Marine Monitoring, Saltwater Testing.Dual Sacle: 0-100ppt & 1.000-1.070 Specific Gravity
Feature
Upgraded QualityPartable Hard Storage Box
Dual Salinity Scale
Automatic Temperature Compensation
Full 12 Month Replacement Warranty
Description
Brand new Salinity Refractometer that is used to measure the salinity levels of saltwater aquariums and the worlds oceans. Calibrate with either distilled water or a 35ppt Salinity standard. Wipe off the saltwater after each use. This unit comes with Automatic Temperature Compensation or "ATC". This feature allows you to get a reading outdoors when the temp is between 50'F-86" (10'C-30'C). If you test outside of temp range your readings will become gradually more and more inaccurate. For best results, test indoors. No batteries necessary as you only need strong light - daylight (sunny or cloudy) or a lamp/flashlight.2.

Features automatic temperature compensation.
Comes with hard case, dropper, screwdriver, user manual and cleaning cloth.
The main part is made of chromium, it's very durable.
Description
Refractometer for seawater and marine fishkeeping aquarium 0-100 pptDetails :
This optical refractometer (salinity meter) has scales in the range of 0 - 100 ppt(0 - 10 %). The reading resolution is 1 ppt. It is designed for the measurement of seawater (marine aquaria) or very low concentrated salt solutions.
The second scale is for reading of the salt solution density in range 1.000 to 1.070 g/cm3 (resolution 0.001 g/cm3).
The usual salinity of the selected aqueous solutions
1.Fresh water ---< 0.5 ppt
2.Brackish water---0.5 to 30 ppt
3.Saline water (Seawater)---30 to 50 ppt
4.Brine---> 50 ppt
(Salinity 36 ppt means, that there are 36 grams of salt in 1 liter aqueous solution.)
Measurement:
The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary)
and you will be able to read the result value on the scale.
