LS313 Rechargeable Salinometer
Rechargeable model, long-lasting lithium battery life.
Home Kitchen/Seawater/Aquaculture Salinity Detection
Simultaneously measures 6 parameters including TDS, conductivity, and salinity
Identifies water salinity levels, with two types: freshwater and saltwater
Color screen with intelligent classification, making water quality assessment more convenient
LS313 Rechargeable Salinity Meter, suitable for daily home cooking, light catering stores, small freshwater aquaculture, and other usage scenarios. A single measurement provides six water quality parameters: salinity, hardness, specific gravity, TDS, conductivity, and temperature, and displays two salinity levels—freshwater and saltwater—based on the screen's backlight color. Paired with a color screen salinity grading and mini-program data management function, daily testing is efficient and convenient. The built-in rechargeable lithium battery offers long-lasting endurance for extended use, making long-term use more worry-free and environmentally friendly.

Product Features
Six-parameter simultaneous detection
A single measurement covers six core parameters: salinity, hardness, specific gravity, TDS, conductivity, and temperature, making it widely applicable across various scenarios such as soup bases, brine, and aquaculture.
Color screen display, salinity status at a glance.
Automatically switches backlight color based on salinity: freshwater displays blue, saltwater displays green. The two-level determination is intuitive and clear, allowing quick assessment of the water's salinity range without repeatedly checking the values.
Built-in rechargeable lithium battery, low power consumption.
Equipped with a rechargeable lithium battery, it can measure continuously for 24 hours on a full charge. It offers lower long-term usage costs and is more environmentally friendly, making it suitable for family kitchens that require daily testing.
High-temperature-resistant probe design
The instrument uses a high-temperature-resistant probe, which can withstand temperatures up to 99°C and can directly measure hot soup stock.
Pen-style design, ready to use anytime without burden.
Pen-shaped design is lightweight and compact, making it easy to carry for store inspections and outdoor farming testing.
High-sensitivity probe for more accurate measurement.
The probe's waterproof rating can reach IP67.
Freely switch between % and ppm salinity units
