Salinity Meter for Accurate Salt Concentration Testing

APPLICATIONS

• Salinity Meters for Aquaculture & Prawn Farming
  Maintaining precise salinity levels is critical to the health and survival rates of marine species in aquaculture operations. Prawn farms, oyster hatcheries, barramundi ponds, and ornamental fish breeding facilities all require reliable, repeatable salinity measurement to manage osmotic stress and disease risk. Our portable salinity meters offer rapid in-pond readings without removing water samples, while bench models support laboratory water chemistry analysis. Key features to look for in aquaculture applications include a wide salinity range (0–100 ppt), automatic temperature compensation (ATC), and data logging for trend analysis across multiple ponds or tanks.
• Pool Salinity Meters for Salt Chlorinator Testing
  Salt-water pool systems require precise sodium chloride (NaCl) concentrations — typically between 3,000 and 5,000 ppm — to function correctly. Too little salt results in insufficient chlorine generation; too much accelerates corrosion of pool equipment and irritates swimmers. A dedicated pool salinity meter eliminates guesswork and allows pool technicians and homeowners to verify salt levels in under 60 seconds. Our digital salinity meters and NaCl refractometers are an essential tool for pool service professionals and residential pool owners across Australia.
• Food-Grade Salinity Testers for Processing & Quality Control
  From cured meats and cheese brine to pickle solutions and seafood processing, salt concentration directly affects product safety, shelf life, and flavour. Food manufacturers and quality control laboratories rely on accurate, food-safe salinity meters to meet production specifications and comply with HACCP requirements. Our range includes digital refractometers and portable meters specifically calibrated for NaCl measurement in food matrices, with stainless probe materials suitable for food contact.
• Environmental & Water Quality Salinity Monitoring
  Estuarine and coastal ecosystem health depends on stable salinity gradients. Environmental scientists, catchment management authorities, and water utilities use field-portable salinity meters to assess salinity intrusion in freshwater systems, monitor aquifer salinisation from irrigation, and track estuarine mixing zones. Our instruments support measurement in natural water matrices across a wide conductivity range, with options for GPS-tagged data logging when integrated with field survey workflows.

Salinity Refractometers: Optical Precision for Sea Water & Aquarium Use

A refractometer measures salinity optically — by bending light through a liquid sample — rather than electrically like a conductivity-based salinity meter. This makes refractometers the preferred choice for marine aquarium keepers, seawater analysis, and food-grade NaCl testing, where a drop of sample and a quick eyepiece or digital reading is faster than probe-based measurement. Our range covers both optical and digital formats: the MR100ATC (0–100% salinity, wide-range optical) and MR110ATC (0–10% salinity, fine-resolution optical) both include Automatic Temperature Compensation (ATC) for accurate readings without a warm-up period, while the MR128ATC is purpose-built for sea water density. For digital precision, the Milwaukee MA887 gives a direct digital salinity readout for seawater and aquarium use, and the Milwaukee MA886 is calibrated specifically for sodium chloride (NaCl) measurement in food and brine applications.
