Instant Ocean SeaTest Hydrometer Information

Part #: 02503

Test and monitor the salinity and water quality of your aquarium water efficiently and effectively with the Instant Ocean SeaTest Hydrometer from Pet Store. This measuring tool is a must-have for aquarists, whether beginners or experts. It allows them to determine if the water environment of their pets is safe conveniently. This also helps them correct the factors that contribute to the cause of poor water quality and improper levels of salinity.

This hydrometer comes in an improved design that enables it to deliver better performance. It can precisely gauge and reveal full-range salinity of the water and its specific gravity. It is so sensitive that it can read up to 0.001 accurately at all times. The hydrometer features an easy-to fill-container that prevents dripping when filling, keeping your hands clean and dry while testing the water. It comes with a durable, stable needle mount and a dual-color scale, which is simple to read and understand. The "safe zone" and wide stabilizer base allow you to gauge the water quality faster and react more appropriately when they indicate dangerous levels of salinity.

The Instant Ocean SeaTest Hydrometer is perfect to use in water with temperatures ranging from 68°F up to 85°F. It can be used in tanks of all sizes and quantities of water.

Instant Ocean Hydrometer`s new improved design delivers precise full-range salinity and specific gravity readings - accurate to 0.001 - every time. Easy-fill convenience keeps hands dry when filling. It has a durable, permanent needle mount and easy-read 2-color scale with "safe zone" and an extra-wide stabilizer base. Ideal for use in water temperatures of 68 - 85°F.

Great item for price Product Review by JOHN J (Posted on 3/6/14)

Comments: I have been able to keep my livestock healthy for at least 10 years using this product. While not as accurate as a refractometer, it's very close. I have two of these and they test only about .002 higher than the refractometer. For the price and ease of use it's a great way to get started and keep your hands dry. Clean up with tap water is a breeze. Also this item is very easy to read without glasses or bright lights. Some other reviews claim this item was reading way off in terms of accuracy. These can get clogged up with salt if water is left too long...Also this item requires a seasoning period for about 24 hours...You put salt water in there for a day before normal use...do this only when you first get it or after a harsh cleaning. Great product

Great once you get hang of it Product Review by emzee (Posted on 2/26/14)

Comments: I bought this hydrometer, and at first had problems with getting inconsistent and high readings. The trick is learning how to get the water in without bubbles sticking to the pointer. If you slowly lower it into the water with the semicircular part facing down (i.e. long flat side on top), then rotate it into the vertical position while underwater, then gently take it out, it comes out bubble free and quite accurate (I found it consistently reading 0.001 lower than a refractometer). So for the money, it is great, unfortunately it is not operator error proof.

Good Product Review by Fred Oehmke (Posted on 3/26/14)

Comments: I have used this type of hydrometer in the past and continue to use it as a cheap backup. These instruments are fairly accurate and good to have around. I always check against a refractometer to determine how close the hydrometer is. I have not seen one that has been right on and I have seen some as far off as 1.005 from actual...that is enough to upset certain inverts and species sensative to salinity. Good product for what it is. Thanks MarineDepot for the great service

good product Product Review by KIEL FRIEDT (Posted on 2/26/14)

Comments: good overall product use it for all my tanks but of course a Refractometer is always better but this is still great.

Easy and accurate! Product Review by bear (Posted on 2/26/14)

Comments: No problem with this easy to use plastic hydrometer! Follow directions and rinse in ro/or tap w/out salt before and after use!
