Water Treatment Process Instruments
Online Conductivity Meter
product details

Product model: 2210


Product Overview


The online conductivity meter has the characteristics of full Chinese display, Chinese menu operation, full intelligence, multifunctionality, high measurement performance, and strong environmental adaptability. It is widely used in industries such as power, chemical, environmental protection, pharmaceuticals, metallurgy, biochemistry, food, and water supply. Electrodes with electrode constants of 0.01, 0.1, 1.0, or 10 can be selected based on the range of conductivity of the tested water sample, and installed in a flow through, immersion, or flange style.
