LS310 Multi-parameter TDC Water Quality Tester High Precision Quality Monitoring for Drinking/Running Water

LS310 Multi-parameter TDC Water Quality Tester High Precision Quality Monitoring for Drinking/Running Water

Description:
- LS310 water quality tester is an instrument dedicated to testing the quality of drinking water. The COD, TOC and UV275 water quality parameters of drinking water are measured by ultraviolet absorbance method, and the TDS and conductivity of drinking water are obtained by measuring the conductance between electrodes.
- The instrument can measure 6 water quality indicators at the same time, and judge the water quality in an all-round way. At the same time, it has an intelligent scoring function, which can quickly judge the water quality level.
- The color of the LCD backlight indicates the four levels of excellent water quality, good water quality, average water quality and poor water quality.
- LS310 water quality tester is mainly used to detect drinking water such as tap water, purified water and underground water.

Features:
- Smart scoring, indicating 4 different levels. The water quality is scored according to the Chinese drinking water standard, which corresponds to 4 grades: Fine quality, good quality, average quality and poor quality.
- Six water quality parameters can be measured simultaneously without reagents. Simultaneously measure COD, TOC, UV275, TDS, EC, and temperature without any reagents to assess water quality in all aspects.
- Indirectly reflect the residual chlorine content in water. UV275 indirectly indicates the residual chlorine content in water, the higher the residual chlorine content, the higher the UV275 value
- Compact and easy to carry with pen design.
- Sensitive probes for more accurate measurements.
- Probe is waterproof and complies with waterproof rating IP67.
- Easy to operate, one-button measurement.
- Adopt TFT color screen design, blue, green, yellow and red display.

Detection of 6 indicators: TDS, COD, TOC, UV275, TEM, EC
- COD chemical oxygen demand: Organic matter, nitrite, sulfide, ferrous salt
- UV275 ultraviolet absorption value: Indirectly reflect the residual chlorine humus type macromolecular organic matter, aromatic compounds
- TOC total organic carbon: Bacteria, viruses, microorganisms, humic substances, chemical pesticides, toxic substances
- EC electrical conductivity: The ability of the solution to conduct current
- TEM temperature: Water temperature (breeding temperature measurement, etc.)
- TDS total dissolved solids: Calcium chloride, sodium chloride, magnesium sulfate, potassium sulfide

Indicator Analysis:
- TOC (mg/L) total organic carbon: Carbon is the common component of all organic matter, the main element of organic matter, the higher the TOC value of water, the higher the organic content of water, total carbon is an indicator to evaluate the organic pollution of water quality.
- COD (mg/L) chemical oxygen demand: Measure the amount of reducing substances that need to be oxidized in the water sample, a comprehensive reflection of the degree of organic pollution of the water, the lower the value indicates that the water is polluted by organic pollutants, the lower the degree of pollution
- UV254 (au/cm) ultraviolet absorption value: The absorbance of some organic matter in water at 254nm wavelength, reflecting the number of various types of macromolecular organic compounds in water
- EC (au/cm) electrical conductivity: Theoretically H2O non-conductive liquid in the more charged substances the greater the conductivity of the liquid, commonly used in various industries to measure the concentration of the solution
- TEM (℃) temperature: Measure the temperature change of water
- TDS (ppm) total dissolved solids: The total amount of various ionic molecules and compounds dissolved in water, the higher the TDS value, the more dissolved substances contained in the water.
