DDG-2090A Industrial online Conductivity Meter has special price advantages due to its

simplified functions on the premise of unaffected performance. 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.                          

♦ Multi-parameter measurement, temperature compensation and automatic range conversion are

achieved thanks tothe high-performance CPU chip, high-precision AD conversion technology

and SMT pasting technology, resulting in high precision and repeatability.

♦ Reliability: Touch keys, no switch knob or potentiometer.
♦ Alarm: Isolated output of alarming signals, discretionary setting of upper and lower thresholds for

alarming, and lagged cancellation of alarming.
♦ Isolated current output: Discretionary setting of upper and lower thresholds of current corresponding

to the conductivity.
