Fit for brackish and marine aquariums
Specific Gravity and Salinity PPT Scales
Optimal Specific Gravity / Salinity range indicator on scale
Bubble diffuser on water intake prevents micro-bubbles from forming on needle
Extra-Wide Stabilizer Base
Easy Fill convenience — NO WET HANDS!
1. Insert the hydrometer into the tank or the fish pond until thespills the plate. (slowly fillingto prevent bubbles attached to the pointer)
2.When thereaches the full state, take out the hydrometer and place it on a horizontal surface.
3.The air bubbles attached to the needle will lead to inaccurate reading, carefully using the stick to blow the foam to make the bubble dismissing.
4.Read the specific gravity according to the inner scale, and read out the salinity (PPT) according to the outside scale. We recommend that the seadensity of the seafood pool is between 1.020-1.023, that is the safety line.
5.Rinse with cleanafter each use.
Item Type: Salinity Tester
The proportion of range: 1.000-1.030
Salinity range: 0-43.9
Length x Height x Thick: 8.5*12.8*1cm/3.3″*5″*0.4″
Note: the first use of hydrometer, fill the warmand detergent, cleaning theof oil clean inside, can make higher accuracy.
Cleaning: salt crystallization on the pointer will cause inaccuracy of reading. If the salt isin the hydrometer, the hydrometer can be soaked in warmor vinegar for 30 minutes, then washed and dried with clean water.
