CM-230D Intelligent Conductivity Measurement and Control Instrument is cheap, welcome to purchase!

CM-230D Intelligent Conductivity Measurement and Control InstrumentFeatures and Applications:
Keyboard style setting of electrode constants, with the ability to set upper and lower values for over limit alarms. By switching with buttons, the medium temperature, μ S/cm, and ppm (TDS) conversion can be viewed, with automatic range conversion. Three electrode constants (0.1cm-1, 1.0 cm-1, 10.0 cm-1) can be selected, supporting a wider measurement range.
Ultra stable measurement acquisition, wide temperature and low drift design, measurement status can be switched between conductivity/temperature/TDS, water quality exceeding alarm function, high brightness background light LCD display.
Suitable for online monitoring and control of electrodialysis, reverse osmosis, ion exchange water production systems, cooling water control systems, and general industrial water.
