  Details:
Overview
DDG-2090XZ industrial online conductivity meter is a new-generation whole English PC-type instrument, characterized by display fully in English, high smartness, multiple functions, high measurement performance and strong environment adaptability. It can be widely used for continuous monitoring of solution conductivity in such industries as thermal power, chemical engineering, fertilizer, metallurgy, environmental protection, pharmacy, biochemical engineering, food and water supply. The secondary meter with constant electrode is 1 or 10 can measure the conductivity of common liquids ; which matched 0.1 or 0.01 electrodes, can accurately measure the conductivity of water or ultra pure water, on-line continuous monitoring is particularly suitable for power plant boiler feed water steam condensate water and high pure water.


Features
English display, English operation menu structure: DDG-2090XZ type function menu operation method, easy to operating.

Intelligent: DDG-2090XZ English online conductivity meter adopts high precision AD conversion and single chip micro processing technology, to complete the measurement of conductivity and temperature, automatic compensation, automatic range conversion and instrument self checking.

Strong anti-interference ability: Current output using photoelectric coupling isolation technique, strong anti-jamming capability to realize remote transmission. There is electromagnetic compatibility.

25℃ Conversion : Conductivity value of the current temperature 25 ℃ respectively, to achieve the conductivity value of the display at 25 ℃, is particularly suitable for power plant a variety of water quality measurement.
