DDG-2090 Industrial online Conductivity Meter is developed on the basis of guaranteeing the performance and the functions. The clear display, simple operation and high measuring performance provide it with high cost performance. It can be widely used for continuous monitoring of conductivity of water and solution in thermal power plants, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemical engineering, foodstuff, running water and many other industries.
Main Features:
The advantages of this instrument include: LCD display with back light and display of errors; automatic temperature compensation; isolated 4~20mA current output; dual relay control; adjustable delay; alarming with upper and lower thresholds; power-down memory and over ten years of data storage without backup battery. According to the range of resistivity of the water sample measured, the electrode with a constant k = 0.01, 0.1, 1.0 or 10 can be used by means of flow-through, immerged, flanged or pipe-based installation.
