LS312 Salinometer
A Beginner's Choice for Daily Salinity Testing
Household Soup/Seawater/Freshwater Aquaculture Salinity Detection
One-touch measurement of 6 parameters including salinity, hardness, and TDS
Intelligent salinity level judgment with color display on screen
Can be connected to a mini-program for convenient sharing at any time
The LS312 is a portable salinometer designed specifically for everyday household scenarios, suitable for testing low-salinity water bodies such as home cooking, freshwater aquaculture, and daily drinking water. The instrument is easy to operate—simply press a button to measure six water quality parameters: salinity, hardness, specific gravity, TDS, conductivity, and temperature. The screen automatically switches backlight color based on salinity, providing two indicators—freshwater and saltwater—so you can quickly determine salinity without needing to compare numerical values. The device is compact, powered by batteries, and ready to use right out of the box, making it ideal for daily household use and light testing scenarios.

Product Features
One-button measurement of 6 parameters
With just one press, you can simultaneously measure six core indicators: salinity (SAL), general hardness (GH), specific gravity (S.G.), total dissolved solids (TDS), electrical conductivity (EC), and temperature (T), providing a comprehensive understanding of water quality without the need for multiple devices and repeated testing.
Color screen intelligent grading, salinity level visible at a glance.
The instrument automatically identifies the salinity level and switches the backlight color: blue for freshwater and green for saltwater. The results are intuitive and easy to understand.
High-temperature probe design
Whether it's hot soup or room-temperature water, the instrument can measure directly, with the probe capable of withstanding temperatures up to 99℃.
Powered by dry batteries, it can be used anywhere without constraints.
Powered by two AAA alkaline batteries, no charging cable needed, no waiting for charging—just pick it up and use it.
Pen-style design, easy to carry.
Compact and lightweight, it can be directly placed in a kitchen drawer or storage bag, making it easy to carry without any burden. It is convenient for both outdoor and on-the-go testing.
High-sensitivity probe, fast response, accurate measurement
Probe waterproof design, IP67 protection level
Salinity unit switchable, adaptable to different usage habits
