LS310 water quality tester is an instrument dedicated to testing the quality of drinking water. The , TOC and UV275 water quality 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 Detector is mainly used to detect drinking water such as tap water, purified water and underground water.

Features

1. 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.

2. Six water quality can be measured simultaneously without reagents. Simultaneously measure , TOC, UV275, TDS, EC, and temperature without any reagents to assess water quality in all aspects.

3. 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 value4. Compact and easy to carry with pen design.

5. Sensitive probes for more accurate measurements.

6. Probe is waterproof and complies with waterproof rating IP67.

7. Easy to operate, one-on measurement.

8. Adopt TFT color screen design, blue, green, yellow and red display.




Wide range of applications


It is mainly used for testing drinking water such as tap water, purified water and groundwater.




Intelligent scoring, indicating 4 different levels.


Water quality is scored according to Chinese drinking water standards, corresponding to indicate fine quality, good quality, average quality and poor quality 4 levels




No reagents, measuring 6 water quality simultaneously.


Simultaneously measures , TOC, UV275, TDS, EC, and Temperature without any reagents to assess water quality in all aspects.




Indirectly reflect the residual chlorine content in water.


Indirectly indicates the residual chlorine content of water through the UV275, the higher the residual chlorine content, the higher the UV275 value.




Compact and portable


Compact and easy to carry with pen design.




Highly sensitive probes


Sensitive probes and high precision temperature sensors for more accurate measurements.




Easy to operate


Easy to operate, measure water quality at touch of a on.




Waterproof probe


Probe is waterproof and complies with waterproof rating IP67.




Bacteria, viruses and pesticide residues all reflectConclusion: LS310 can reflect E. coli in water, while TDS pen cannot




Conclusion: LS310 can reflect the pesticide residues in the water, while the TDS pen can not




Detection of 6 indicators: TDS, , TOC, UV275, TEM, EC

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




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.




(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.
