Salinity Refractometer With 1.3 x Magnification Of The Marking

Product Size (cm): 150x580
Salinity Refractometer is 100% accurate, no more wondering if the hydrometer is still accurate, calibrated or consistent.
These devices never wear out and only require two drops of tank water to conduct the test.
They have automatic temp control from 10 - 30 degrees. You need to calibrate it in a room thats + - 20 degrees for best results.

Maintaining a stable salinity is one of the most important aspects of reef tank husbandry. Gone are the days when the serious hobbyist relied on Hydrometers to keep tabs on this crucial parameter. Now these vital measurements are easily monitored with the Aqua-House ™ Refractometer.
Easy to Read

Each Marine Sources; Refractometer features our Clear View oversized display to ensure the easiest, most accurate readings possible in two scales (±1.0% salinity and ±0.001 specific gravity).

se. Additionally, the insulated, non-slip rubber grip will keep external sources of heat, such as hand warmth, from interfering with an accurate sample reading.
Robust Construction

Marine Sources Refractometers have an all-metal body housing for added durability. A large rubber hood both provides additional protection to the eyepiece and prevents foreign light from entering the unit body.
Easy to Use

It takes less than a minute to use the Refractometer. Simply place a few drops of water on the refracting lens and look through the eyepiece and take note of the boundary between blue and white. That's it! You now have an accurate measurement of your tank's salinity.
