🐟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).

Measure salt water or salinity of water, ideal for aquariums and marine monitoring.
Measures on 2 scales, Specific Gravity (D 20/20) and parts per thousand.
Features automatic temperature compensation.
