Water quality cod analyzer is widely used in field measurement, flow monitoring, on-site rapid measurement, and laboratory accurate analysis, especially suitable for environmental monitoring station inspection monitoring
.
When the pH of water changes abnormally, it means pollution
.
Water that is too acidic has a corrosive effect on metals and can promote metal dissolution, which may cause acute and chronic metal poisoning
.
Water that is too alkaline will affect the sense of taste, has a soapy smell, and also has a corrosive effect
.
pH is not a criterion for judging whether water quality is good or bad, but it is a necessary condition
.
After the Wenchuan earthquake that year, in order to judge whether the water source in the disaster area can be drunk, the environmental protection department monitored the drinking water source in the disaster area, and the first indicator was the pH value
.
TDS refers to the total amount of dissolved substances in water, including organic and inorganic substances
.
The higher the TDS value, the more
substances are dissolved in the water.
In the WHO standard, the water contains an appropriate proportion of minerals and trace elements, and exists in an ionic state, which means that the TDS value of healthy drinking water cannot be too low or even 0, and the requirements of the comprehensive national standard cannot exceed 1000mg/L
.
Salinity: mainly refers to the composition of sodium chloride, salt has a bactericidal effect, and people with occasional bacterial diarrhea can reduce symptoms
by drinking salt water.
However, too high salinity not only has a salty feeling, but also causes a burden on the kidneys when drinking regularly, generally not more than 400mg/L
