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 (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

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.

The instrument has ambient temperature compensation function, allowing long-period calibration

Sensitive probes for more accurate measurements

High precision temperature sensor, accurate temperature measurement

Probe is waterproof and meets the waterproof rating IP67
