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.
Features
Multi-parameter measurement, temperature compensation and automatic range conversion are achieved thanks to
the 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.
