  • 【SPECIFICATION】The reading is temperature-corrected and accurate to +/-0.001. The unit of specific gravity is 1. 000-1. 030 (ppt value: 0-40 degrees), the safe area is 1.020-1.023 (ppt value: 27-31 degrees), and the low specific gravity area is 1.000-1.019 (ppt value: 0- 26 degrees), the higher specific gravity area is 1.024-1.030 (ppt value: 32-40 degrees)(Note: PPT value indicates salinity in the outer range of the scale)
  • 【MATERIAL】The salinity tester is made of transparent acrylic material, which is relatively hard and easy to read the salt and specific gravity of your marine aquarium
  • 【 DESIGN 】 The easy-to-read swing arm pointer and ultra-wide stable base provide accurate test results
  • 【APPLICATION】The aquarium saltwater hydrometer can perfectly test the salinity and specific gravity of brackish water and marine fish tanks, including the solubility and specific gravity scale. At the same time, it is very suitable for fresh water and sea water
  • 【NOTE】Before using the salinity hydrometer tester for the first time, fill it with warm water and wash it with detergent before using it. After use, immerse the salt water meter in weak acid (vinegar) for 30 minutes, rinse with tap water and air dry


Product Description

Aquarium Salinity Tester

Specification

The reading is temperature-corrected and accurate to +/-0.001；

The unit of specific gravity is 1. 000-1. 030 (ppt value: 0-40 degrees)；

The safe area is 1.020-1.023 (ppt value: 27-31 degrees)；

The low specific gravity area is 1.000-1.019 (ppt value: 0- 26 degrees)；

The higher specific gravity area is 1.024-1.030 (ppt value: 32-40 degrees).

(Note: PPT value indicates salinity in the outer range of the scale)

Warm tips:

1, Insert the hydrometer to below 15 centimeters of the tank or fish pond until the water overflows the stall.

2, When the water reaches full state, take out the hydrometer and place it on a level surface.

3, Air bubbles adhering to the needle will cause inaccurate readings, carefully tap the hydrometer to shake out the adhering air bubbles.

4, Read the specific gravity according to the inner scale and the salinity (PPT) according to the outer scale. It is recommended that the specific gravity of seawater in seafood pools is between 1.020-1.023, i.e. within the safety line.

5, square type: specific gravity range: 1.000-1.030 salinity range: 0-40

6, rinse with water after each use.

Main features:

*Seawater specific gravity meter that can float on water surface;

*Seawater specific gravity, salinity and conductivity are displayed at one time;

*Simple to use and easy to read;

Inexpensive but the ink is faded and hard to read .

Doesn’t work as readings inconsistent and wide-ranged!
