Digital Specific Gravity/Salinity-Meter (DSG-10) : Monitoring the salt level in a reef aquarium is one of the most basic and important parameters to ensure a safe and optimal environment for tank inhabitants. Many organisms are not equipped for high tolerances in shifts in temperature,salinity and specific gravity for long durations without fatal consequences. The DSG-10 Meter is an innovative 3-in-1 tool that incorporates digital tests for temperature(C),salinity(ppt) and specific gravity (e.g. 1.024) displayed in scales commonly used by aquarists without the need for conversions. This revolutionary meter alllows hobbyists to receive precise, accurate, and reliable readings with the press of a button! ADVANCED FEATURES 3-In-1 The only digital meter that tests for temperature, salinity, and true specific gravity Auto-correct Automatic temperature compensation that calculates for salinity and specific gravity without the need for complicated conversion charts |
