| DDG-2090 series of microcomputer-based industrial control instruments are precision meters for measurement |
| of conductivity or resistivity of solution. With complete functions, stable performance, simple operation and |
| other advantages, they are optimal instruments for industrial measurement and control. |
| 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. |
