0.01 ~ 20μs / cm Industrial Conductivity Meter DDG-2090A

DDG-2090A Industrial Conductivity Meter DDG-2090A conductivity meter is based on the simplified guarantee performance, which has a particularly strong price advantage. Clear display, simple operation and excellent performance makes the test very high price. It can be widely applied to a continuous monitoring of thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and running water conductivity value of the solution. Instrument features: Microprocessor: the use of high-performance CPU chip, high-precision AD conversion technology and SMT Stamp technology to complete the multi-parameter measurement, temperature compensation, the amount is automatically converted into a high precision and good repeatability. Reliability: touch buttons, no switches knobs and potentiometers. Automatic conversion measurement frequency: avoid electrode polarization, improve measurement accuracy. Alarm function: alarm signal isolation output, alarm upper and lower limit can be set arbitrarily, alarm hysteresis withdrawn. Networking: Isolated current output and RS485 or RS232 communication interface isolated current output: the output current corresponds to the electrical conductivity, the lower limit can be set Specifications: 1.
