DDG-2090A industrial conductivity
●Overview
DDG-2090A conductivity meter is simplified on the basis of guaranteed performance, which has a particularly strong price advantage. The clear display, simple operation excellent test performance make it have a high cost performance. It can be widely used for continuous monitoring of conductivity values in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food, tap water.
●Features
● Microcomputerization: Adopt high-performance CPU chip, high-precision AD conversion technology SMT ticketing technology to complete multi-parameter measurement, temperature compensation, automatic conversion of volume, high precision good repeatability
● Reliability: Touch buttons, no switch knob potentiometer
● Alarm function: Alarm signal isolated output, upper lower alarm limits can be set arbitrarily, alarm lag cancel
● Isolated current output: the upper lower limits of the current output corresponding to the conductivity can be set arbitrarily
