Apure A10 digital conductivity meter
Apure A10 digital conductivity meter for water
A10 industrial conductivity (TDS) instrument is intelligent upgrade product of ES-2200 industrial conductivity instrument. The electrical conductivity (TDS) value of various industrial water can be continuously measured and controlled. The device is widely used in scientific experiment equipment, chemical, pharmaceutical, environmental protection, metallurgy, papermaking, food, beverage and water supply industries.
What is the purpose of the conductivity meter?
Conductivity meter (EC meter) mainly measures the conductivity value in solution. It has a variety of scientific and engineering applications and is commonly used in hydroponics, aquaculture, freshwater systems and water treatment industries to monitor the amount of nutrients, salts or impurities in water.
Why to say the measurement of water conductivity value is very important?
In general, the higher conductivity value shows that the water dissolved chemicals. Conductivity measuring water conductive ability. As a result of the dissolved salt conduction current and other inorganic chemicals, electrical conductivity increases with the increase of salinity.
