Dymax Glass Hydrometer

Ensure optimal salinity and stability in your marine ecosystem with the Dymax Glass Hydrometer. Combining a floating hydrometer and a precision built-in thermometer, this dual-action 2-in-1 testing instrument provides quick, accurate readings of both specific gravity and water temperature in your saltwater aquarium.

Crafted from high-clarity, durable glass, it features an easy-to-read printed scale that allows hobbyists to monitor parameter shifts instantly and maintain perfect salinity levels for corals, fish, and invertebrates.

Key Features & Benefits

• 2-in-1 Design: Measures both specific gravity and water temperature in a single floating glass tube.

• Easy-to-Read Scale: High-contrast markings allow for precise, clear readings at a glance.

• Multi-Parameter Monitoring: Helps monitor specific gravity, salinity, and conductivity parameters to keep marine life thriving.

• High-Clarity Durable Glass: Engineered from durable glass designed for safe, long-term use in aquarium testing jars or sumps.

• Essential Marine Tool: Vital for salt mixing, water changes, and routine salinity checks in saltwater reef and fish-only setups.

How to Use

1. Fill a clean testing jar or tall container with the aquarium water you wish to test.

2. Gently lower the Dymax Glass Hydrometer into the liquid.

3. Give the hydrometer a quick twirl to dislodge any trapped air bubbles on the glass surface.

4. Allow the hydrometer to settle freely away from the container walls.

5. Take your reading at the lowest point of the water's surface (the bottom of the meniscus) along the floating scale.
