SunGrow Aquarium Salinity Refractometer — Precise Readings, Easy Calibration

Designed for Saltwater Success

SunGrow Measure Salinity for Saltwater Aquariums is tailored to seawater testing, offering readings that reflect the realities of marine and reef setups. This model is calibrated specifically for saltwater, helping you move beyond generic readings and toward data you can trust when planning water changes or assessing tank health.

Smart Calibration for Real-World Changes

Temperature drift is a common challenge in hobby rooms and office corners. With automatic temperature calibration, readings stay reliable as ambient temperatures swing between 50° F and 86° F. The result is consistent data you can rely on, even when your tank room experiences a quick temperature shift.

Easy Reading for Saltwater Aquariums

A focused eyepiece and a crisp optical line provide clear readings, making it easier to verify salinity levels before acclimating new livestock or performing routine maintenance. The hands-on ease helps you verify results quickly during busy days.

Everything You Need in One Case

The kit arrives in a solid, protective hard case and includes a calibration tool and a pipette. This all-in-one setup supports safe storage, simple transport between tanks, and ready testing wherever you keep your equipment.

Why Salinity Matters in Reef Tanks

Maintaining proper salinity supports marine life and plant health. In reef and marine aquariums, a target salinity around 35 ppt is commonly referenced, helping you gauge evaporation and water changes with greater confidence.

• Specifically designed for saltwater testing, not a general-purpose refractometer.
• Automatic temperature calibration prevents readings from drifting with room temperature changes.
• Clear reading and adjustable eyepiece for precise, easy checks.
• Durable hard case, calibration tool, and pipette simplify storage and testing on the go.
• Regular checks help you align measurements with reef tank targets, supporting stable conditions.

Using the SunGrow refractometer can streamline your reef-keeping routine, reduce guesswork, and provide dependable data during water changes, livestock introductions, and routine maintenance. While readings offer valuable insight, pair them with a broader monitoring plan for best results.
