Product Description

DUAL SCALE - The Saltwater Refractometer measures specific gravity (D20/20). 000-1. 070 and parts per thousand 0100 (1=1ppt=1000ppm) allow you to obtain results in two different units from a single test.

VERSATILE APPLICATIONS - The Refractometer is ideal for aquariums, marine monitoring, agriculture, and gardening. To assist you in controlling the concentration of salt water, you can test its concentration.

EASY TO USE - After calibrating the prism, place 2-3 drops of sample solution toward the light to obtain accurate readings. The Hallocool aquarium refractometer is a great alternative to expensive digital salinity testers or salinity hydrometers.

ATC FUNCTION - The Automatically Temperature Compensate function on this aquarium salinity refractometer ensures that refractometers always give accurate readings quickly and easily.

LONG-LASTING Refractometer that can be carried around in a plastic case.

The quality and value are incredible

5/5

I use this saline refracftometer to measure the salt level in the water when raising brine shrimp, and it's more than adequate for a hobbyist. Excellent quality and precision, with a nice protective case included. I'm very pleased.

The fish store had been selling it for three times the price for quite some time

4/5

So this was a good deal; however, it's a little difficult to see and requires good lighting.

The hydrometer that was sent was the wrong one

3/5

Mine doesn't show salinity or any other information that would be useful in my reef tank. I believe the hydrometer I received was incorrect. It works well and is reasonably priced; however, it is not something I can use, and I wish I had been sent the correct one.

Simple

5/5

The interface is straightforward. The text is simple to follow. The value for money is there. To me, it appears to be a good entry-level tool for newcomers.
