DDG-2090D 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.          

♦ Multi-parameter measurement, temperature compensation and automatic range

conversion are achieved thanks to the high-performance CPU chip, high-precision

AD conversion technologyand 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 
♦ Isolated current output: Discretionary setting of upper and lower thresholds of

current corresponding to the conductivity.
