High Precision Tropic Marin Hydrometer


Use this High Precision Hydrometer by Tropic Marin to determine the salinity of your aquarium water by measuring its specific gravity. This handmade instrument is designed to float vertically in the water and has a maximum deviation of 0.001 at 77 degrees Fahrenheit (25 degrees Celsius). It is an extremely accurate and reliable tool that can even serve as a reference point for other instruments. Best of all-- the Tropic Marin Hydrometer never requires re-calibration! 

Features:
  • Measures salinity with high precision
  • Never needs to be re-calibrated!
  • Can be used to fine-tune other equipment
  • Max. deviation: 0.001 at 77° F (25° C)
  • Scale from 1.021 to 1.031
  • Resolution: 0.0001
  • Handmade

How to Use:
Transfer aquarium water into a testing jar or cylinder with sufficient volume to fully suspend the hydrometer.

Ensure that your test water is at 77 degrees Fahrenheit (or 25 degrees Celsius).

Place the hydrometer in the testing cylinder and allow it to buoy. It is recommended that your hydrometer be centered and fully vertical for the most accurate reading. Take your reading from the level where the surface of the water and hydrometer intersect.

Tropic Marin
Tropic Marin: A strong foundation in science and hobby: The successful methods and techniques of today`s marine aquarists are the result of a close collaboration between serious hobbyists, scientists and specialists at public aquariums. Tropic Marin came about in exactly the same way over 30 years ago! This close cooperation resulted in one of the first complete one-part synthetic marine salt mixtures that provided the optimum natural environment for the professional as well as the private aquarist.

This product is not designed to be continually stored in the water and for the most accurate readings we recommend using it just for testing.

PROS
High accuracy, simple, almost no maintenance, inexpensive
CONS
Fragile, need fairly still water which is at least 15 inches deep
REVIEW
I bought this as a backup for my Milwaukee digital salinity meter. After using it a few times, it's become my primary method to test salt content of my reef tank. I prefer this hydrometer better because there is no need to worry about calibration, replacing calibration fluid, varying light condition...Read More
