Description
LS310 tds 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 water quality tester can measure 6 water quality indicators at the same time, and judge the water quality in an all-round way. At the same time, the tds water quality tester 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 for drinking water is mainly used to detect drinking water such as tap water, purified water and underground water.
Please use distilled water or medical distilled water for calibration. Do not Use Mineral Water for calibration
Features
1. Smart scoring, indicating 4 different levels.
2. Simultaneously measure COD, TOC, UV275, TDS, EC, and temperature without any reagents to assess water quality in all aspects.
3. UV275 indirectly indicates the residual chlorine content in water, the higher the residual chlorine content, the higher the UV275 value
4. 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-button measurement.
8. Adopt TFT color screen design, blue, green, yellow and red display.
Wide range of applications
The water quality tester for drinking water 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
Water quality scoring standards
According to “GB 5749-2002 Standards for drinking water quality”
No reagents, measuring 6 water quality parameters simultaneously.
Simultaneously measures COD, TOC, UV275, TDS, EC, and Temperature without any reagents to assess water quality in all aspects.
High accuracy
Passed the authoritative metrology institute inspection
Linshang LS310 digital water quality tester more comprehensive
Bacteria, viruses and pesticide residues all reflect
Measurement results:
LS310 water quality tester professional: Poor water quality
TDS: Unable to detect bacteria and pesticides
Specifications：
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
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.
