Extremely accurate and easy to use swing needle hydrometer.

Provides temperature corrected readings in water that is in the temperature range of 20-29 deg C

Ensure there are no air bubbles attached to the swing arm needle before taking the reading, and wash out with fresh clean water after use

Reads : Salinity (ppt) 0 - 40. : S.G. 1.000 - 1.032

Marine fish and corals require stable water conditions, which makes regular checking of salinity important. It’s also necessary to check salinity when making up new water for water changes.

The TetraTec Hydrometer makes it simple to accurately check the salt content of water, giving precise readings over a wide temperature range (20 – 29°C). It works by measuring the specific gravity (relative density) of the water, and converting this to salinity.

All you need to do is fill up the hydrometer with water, and read the value off the scale printed on the side. 


  £9.24

Easy Dip and Read Hydrometer with swing needle.Measures :

Salinity (ppt) 0 - 40 ppt (at 25 deg C)

Specific Gravity 1.000 - 1.030 (with optimum marine tropical range 1.020-1.023 highlighted) (at 25 deg C)

Rinse with fresh water after use as dried salt on swing needle may effect subsequent readings.
