Why You Need It
Too much or too little salt ruins quality—whether it’s a reef tank, pickling brine, craft beer, or a hotel swimming pool. Our 0-28 % Digital Salinity Refractometer gives you a lab-grade reading in 1.5 seconds with just two drops of sample, so you can tune salinity on the spot.
Key Features
- 0 – 28 % NaCl Range & 1.000-1.217 SG — covers marine aquaria, food brines, and hydroponics.
- ATC & LED Back-light — automatic temperature compensation and clear readings anywhere.
- High Resolution — 0.1 % salinity / 0.001 SG for precise control.
- IP65 Rugged Housing — ABS shell seals out splash & dust for field or kitchen use.
- Auto-Off — saves battery after 3 minutes of inactivity.
Applications
- Salt-water & reef aquarium maintenance
- Pickling / fermentation brine adjustment for kimchi, olives, or soy sauce
- Food & beverage QC — soup, juice, craft beer, kombucha
- Swimming pool & spa salinity checks
- Laboratory & research saline solution preparation
