Lohand Online Conductivity Controller CR300

The online Conductivity meter is an online intelligent Conductivity detector produced by our company with foreign technology. It adopts imported components and Conductivity film heads, based on the latest polarographic analysis technology, advanced production technology and surface mount technology. This series of advanced analytical techniques is used to ensure the long term stability and reliability of the instrument. It has Chinese menu operation, notebook storage measurement data, 485 communication and other functions. Can be widely used in chemical fertilizer,metallurgy, environmental water treatment engineering,pharmaceutical, biochemical, food, aquaculture and tap water and other solutions in the continuous monitoring of Conductivity values.

About Conductivity

Conductivity:The conductivity of water is usually used to indicate the purity of water. If the conductivity is high, it means that the content of conductive minerals in water is very high, and the purity of water is very low. If the conductivity is very low, it indicates the minerals that can be ionized in water. Rarely, the purity of water is relatively high. For example, the conductivity of high-purity water is EC=0.1.0us/cm; the conductivity of ordinary drinking water is 1~10 us/c.
