Hydrometer, Seawater Salt Meter, Aquarium
[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.$0.00 -
hygger Salinity Tester, Transparent Acrylic
🐟Marine hydrometer: Tests salinity and specific gravity in marine aquariums to help maintain a healthy tank
🐟Easy to Read & Use: Simply dunk in aquarium to fill with water, then set on level surface to read. The easy-to-read swing-arm pointer and extra wide stable base provide an accurate test result.
🐟Specification: The reading is temperature-corrected and accurate to +/-0.001. The unit of specific gravity is 1. 000-1. 030 (ppt value: 0-43.9 degrees), the safe area is 1.020-1.023 (ppt value: 30.2-34.2 degrees), and the low specific gravity area is 1.000-1.019 (ppt value: 0- 28.9 degrees), the higher specific gravity area is 1.024-1.030 (ppt value: 35.5-43.9 degrees).$0.00 -
