    DDG-99 series intelligent online conductivity transmitter
     
    Introduction:
    DDG-99 series intelligent online conductivity transmitter is a new generation of intelligent online measurement and analysis instrument developed by our company. It can be equipped with two-pole and four-pole conductivity electrodes. It is widely used in the detection of water conductivity in various industrial processes. , It has the characteristics of high measurement accuracy, fast response, small size, convenient installation and maintenance. Application areas: drinking water testing; boiler water testing; food and beverages; chemical and biological pharmaceutical industries; reverse osmosis/pure water process;
    Features
    1. 16-bit high-precision A/D and high-performance microprocessor technology, complete the conductivity value and temperature parameter measurement, temperature compensation, instrument self-check and other functions.
    2. Graphic dot matrix LCD with LED backlight, which can be operated under direct sunlight.
    3. The range is automatically switched, and the range of the output signal is arbitrarily set for the full range.
    4. Automatic temperature compensation, select the measured water quality according to different working conditions, store multiple compensation curves, and press the button to modify the temperature compensation coefficient and electrode constant. Automatically convert the measurement frequency to avoid electrode polarization and improve measurement accuracy.
