Unfortunately, as we've all experienced, salinity reading equipment as well as calibration solutions can drift over time, and it can occasionally be a challenge to ensure equipment is always calibrated correctly. That's where the Tropic Marin Hydrometer comes in. The Tropic Marin High Precision Hydrometer provides an exact and reliable measurement of specific gravity, and it never needs to be re-calibrated, so it's a perfect reference device for calibrating other equipment.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh precision hydrometer for determining the specific gravity in aquariums\u003c\/li\u003e\n\u003cli\u003eMaximum deviation: 0.001 at 77° F (25° C)\u003c\/li\u003e\n\u003cli\u003eScale from 1.021 to 1.031\u003c\/li\u003e\n\u003cli\u003eResolution: 0.0001\u003c\/li\u003e\n\u003cli\u003eHandmade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe hydrometer is handmade and designed to float vertically in the water.
