LS310 Multi-Parameter Drinking Water Quality Meter

The LS310 water quality measurement device is a special instrument developed to comprehensively measure the quality of drinking water such as tap water, purified water, and groundwater, capable of simultaneously detecting 6 different water quality parameters.

Features

• Specifically designed to test the quality of drinking water.

• Measures water quality parameters COD, TOC, and UV275 using the UV absorbance method.

• 6 parameters it can measure simultaneously:

  • COD (Chemical Oxygen Demand)

  • TOC (Total Organic Carbon)

  • UV275 (Ultraviolet Absorption Value)

  • TDS (Total Dissolved Solids)

  • EC (Electrical Conductivity)

  • Temperature

• Conducts measurements without using reagents.

• COD (mg/L) indicates the degree of organic pollution in the water; the lower the value, the cleaner the water.

• TOC (mg/L) measures the organic carbon content; a high value indicates organic pollution.

• UV275 (au/cm) indicates the amount of organic compounds; a high value is a sign of organic pollution.

• TDS (ppm) represents the total of all dissolved solids in the water; a high value indicates the presence of minerals or pollutants.

• EC (μS/cm) measures the electrical conductivity of the liquid; it depends on ion content and reflects water quality.

• TDS and EC values are determined by measuring conductivity between electrodes.

• The device is used for testing drinking waters such as tap water, purified water, and groundwater.

• The LCD screen displays water quality in 4 levels with backlight color: excellent, good, medium, and low quality.

• Provides easy-to-understand, visual, and comprehensible results.
