Product Description
Professional Salinity Meter for Saltwater Aquariums & Reef TanksThe HM Digital SAL-1700 Aquarium Salinity Meter is the essential tool for maintaining optimal salinity levels in saltwater aquariums, reef tanks, and marine aquaculture. This professional-grade digital meter measures salinity in multiple units (Specific Gravity, PPT, PSU) plus temperature, providing accurate, reliable readings to ensure the health and vitality of your fish, corals, and invertebrates.Key Features & Benefits
Multi-Unit Display: Measures salinity in Specific Gravity (SG), Parts Per Thousand (PPT), and Practical Salinity Units (PSU) for maximum flexibility
Integrated Temperature Sensor: Simultaneous temperature measurement with automatic temperature compensation (ATC) for accurate salinity readings
High Precision: Accurate salinity measurement ensures optimal conditions for marine life
Large LCD Display: Easy-to-read screen shows salinity and temperature simultaneously
Waterproof Design: Durable construction withstands splashes and wet environments
Auto-Off Function: Conserves battery life with automatic shutoff after 10 minutes of non-use
Calibration Function: Simple calibration ensures long-term accuracy
Portable & Convenient: Compact design perfect for testing aquariums, mixing stations, and water changes
Why Salinity Monitoring is CriticalSalinity is one of the most important parameters in saltwater aquariums. Maintaining stable salinity levels is essential for:
Fish Health: Prevents osmotic stress, disease susceptibility, and mortality in marine fish
Coral Growth: Ensures optimal conditions for SPS, LPS, and soft coral calcification and coloration
Invertebrate Survival: Shrimp, anemones, clams, and other invertebrates are extremely sensitive to salinity fluctuations
System Stability: Consistent salinity prevents stress-related issues and maintains biological balance
Water Changes: Verify new saltwater mix matches your display tank before adding
ApplicationsSaltwater & Reef Aquariums: Monitor salinity levels in FOWLR (Fish Only With Live Rock) and reef tanks to maintain optimal conditions. Most marine systems target 1.025-1.026 SG (35 PPT) for fish and corals.Mixing Stations: Verify salinity when preparing new saltwater for water changes, ensuring perfect match to your display tank.Marine Aquaculture: Maintain precise salinity in breeding systems, quarantine tanks, and commercial marine fish operations.Brackish Water Systems: Measure salinity for brackish species like puffers, scats, and monos that require specific salinity ranges.Natural & Artificial Seawater: Test salinity in collected seawater or verify synthetic salt mix concentration.Technical Specifications
