Hydrometer, Seawater Salt Meter, Aquarium Fish Tank Water Test Hydrometer Salinity Measuring Device Tester for Pond Saltwater Fishtank Salinity Tester Aquarium Hydrometers Salinity Meter Water Tester

Features

• [Easy to Use]:Insert the hydrometer at least 15 cm deep into the fishtank (if the insertion line is less than 15 cm, the grease on the fishtank surfaces will affect the accuracy of the test).
• [Automatic Water Level Function]:Based on the internal reading of the scale, Accurate Hydrometer based on the salinity of the horizontal scale (PPT). When the water reaches the state of full water (upper part with guide plate), lift the hydrometer, hung on the cylinder, can automatically find the water level, to avoid errors.
• [Automatic Water Level]:The recommended ratio of water in a fishtank is between 1,020 and 1,023 (safe range). Rinse with water after each use. Fish Tank Pond Water Salinity Tester provide an accurate test result.
• [Application Range]:Aquarium Fish Tank Water Test Hydrometer Suitable for warm water (20-30℃). A change in temperature will cause a change in the reading. Unit specific gravity is accurate to ±0.001.
• [Note]:Bubble attachment on the pointer may cause incorrect reading. Please use the hydrometer to carefully buffer bubble attachment.
