- Simple operation—just press once to quickly determine whether the water meets national drinking-water safety standards.
- The display automatically changes its backlight color according to the water-quality rating: Excellent, Good, Average, or Poor. The interface is intuitive and easy to understand.
- By measuring electrical conductivity, LS311 accurately calculates salinity, general hardness, and specific gravity, helping users gain a complete understanding of the water’s condition.
- The instrument measures: SAL (salinity), GH (general hardness), S.G. (specific gravity), COD (chemical oxygen demand), TOC (total organic carbon), TDS (total dissolved solids), UV275 (ultraviolet absorption value), EC (electrical conductivity), Temperature — providing a full evaluation of water quality.
- LS311 evaluates multiple parameters to give a more accurate and comprehensive rating for mineral and drinking water. A TDS pen alone can be misleading.
- Automatic temperature compensation ensures repeatability and accuracy across different environments, with long calibration intervals.
