NMD-99B Inductive Conductivity/Concentration Transmitter丨Measurement of water conductivity

Product Feature

  • The built-in concentration curves of acids, bases and salts can be accessed by setting and calling the curves to read the concentration values. Users can also create their own required concentration curves.
  • Large-screen LCD display, allowing the selection of displaying various information such as conductivity value, concentration value, temperature, date, and output current.
  • The power supply, measurement and output circuits are isolated from each other, and have strong anti-interference capabilities.

The NMD-99B series conductivity transmitter is a four-wire, single-channel transmitter independently developed by Dongrun Instruments. The transmitter offers more signal output and control functions, making operation more convenient. It is compatible with Dongrun NMD-M_A9 series inductive conductivity sensors.
