LS310 water quality tester is a special instrument for testing the water quality of drinking water, using UV absorbance method to measure the COD, TOC and UV275 water quality parameters of drinking water, by measuring the conductivity between the electrodes to obtain the TDS and conductivity of drinking water. The instrument can measure 6 water quality indicators at the same time, and judge the water quality all-round. LS310 water quality tester is mainly used for testing tap water, purified water and groundwater and other drinking water.

Dangers of drinking poor water quality
Feature
Intelligent scoring, indicating 4 different levels
The instrument through the LCD backlight color indicates fine quality, good quality, average quality and poor quality 4 levels, the measurement results are very intuitive.
No reagents, measuring 6 water quality parameters simultaneously
The instrument does not need any reagent, can measure COD (chemical oxygen demand), TOC (total organic carbon), UV275 (ultraviolet absorption value), TDS (total dissolved solids), electrical conductivity, temperature 6 water quality indicators at the same time, all-round evaluation of water quality.
Indicator Analysis
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
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
UV275 (au/cm) ultraviolet absorption value
Absorbance of some organic matter in water at 275nm wavelength, reflecting the number of various types of macromolecular organic compounds in water
EC (us/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
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.
TEM (℃) temperature
Measure the temperature change of water
Solve the traditional water quality testing pain points
● Traditional water quality testing pain points
● Time consuming laboratory tests by testing institutions
● Large-scale testing equipment and consumables are expensive
● TDS water quality testing index single, can not be true and comprehensive judgment of water quality
● Sudden water quality pollution, the user hindsight
Multi-dimensional parameter scoring
Mineral water is rich in trace elements, avoiding the problem of inaccurate data judged by TDS alone.
Indirectly reflect the residual chlorine content in water
Indirectly indicate the residual chlorine content of water through UV275 indicator, the higher the residual chlorine content, the larger the UV275 value
Pen design, compact and portable
The instrument is designed in pen style, compact and portable, easy to carry and use.
