Multi-channel industrial conductivity meter DDG-2080D

DDG-2080D multi-channel Industrial Conductivity Meter Main features: Dual conductivity meter, conductivity meter three-channel, four-channel conductivity meter, customers can choose, the channels are independent, non-interfering, can simultaneously then four conductance electrodes; Chinese liquid crystal display, Chinese menu. Microprocessor: the use of high-performance CPU chip, high-precision AD conversion technology and SMT technology, complete the multi-parameter measurement, temperature compensation, automatic conversion range, instrument self-test, high accuracy and good reproducibility. Phase sensitive detector design: the elimination of the effects of lead on the measurement. Convert 25 ℃: temperature compensation Automatic Measurement / manual input. Waterproof and dustproof design: protection class IP65, suitable for outdoor use. Isolated 4 ~ 20 mA current output; conductivity value corresponding to the current output, the lower limit can be set arbitrarily.
