Linshang LS310 6-Parameter Drinking Water Quality Tester

The Linshang LS310 is a portable multi-parameter tester for rapid screening of drinking-water quality. Without chemical reagents, it measures COD, TOC, UV275 absorbance, total dissolved solids, electrical conductivity and temperature from a single water sample.

The instrument combines UV absorbance measurement with electrode-based conductivity testing to provide a broader water-quality assessment than a basic TDS meter. A four-level scoring system uses display backlight colors to classify results as fine, good, average or poor for quick on-site interpretation.

Key Features

• Six water-quality parameters: Measure COD, TOC, UV275, TDS, electrical conductivity and temperature from one portable instrument.
• Reagent-free testing: Perform routine screening without preparing or disposing of chemical test reagents.
• COD range from 0–100mg/L: Evaluate the water sample's oxidizable-substance level as an indicator of organic pollution.
• TOC range from 0–100mg/L: Assess total organic carbon to obtain additional information about organic content.
• UV275 absorbance measurement: Measure ultraviolet absorption from 0–1.0AU/cm as another indicator related to organic substances in water.
• TDS measurement: Measure total dissolved solids from 0–2000ppm for evaluating dissolved ionic and molecular content.
• Conductivity measurement: Measure electrical conductivity from 0–4000μS/cm to evaluate the concentration of conductive substances.
• Temperature measurement: Measure water temperature from 0–50°C with automatic ambient-temperature compensation.
• Four-level quality scoring: Use color-coded backlighting to distinguish fine, good, average and poor measurement results.
• Multi-dimensional assessment: Avoid relying on TDS alone when evaluating mineral water and other samples containing naturally dissolved substances.
• 1.14-inch color display: View parameter values and the water-quality classification directly on the instrument.
• IP67-rated probe: Protect the immersed sensing section during routine water-sample measurements.
• Pen-style portable design: The approximately 68g instrument is convenient for on-site and mobile water testing.
• Replaceable battery operation: Uses two AAA alkaline batteries without requiring access to a charging point.

Applications

• Tap-water quality screening
• Purified and bottled water comparison
• Groundwater and well-water checks
• Non-sewage surface-water screening
• Drinking-water source comparison
• Portable household and field water assessment

Why Choose the Linshang LS310?

The LS310 provides a more complete drinking-water screening profile than a single-parameter TDS meter. By combining indicators of organic content, ultraviolet absorption, dissolved solids, conductivity and temperature, it helps users compare water sources and identify changes that warrant closer investigation without carrying multiple meters or chemical reagents.
