DDG-330 Industrial Conductivity MeterDetailed product description：

Characteristics of DDG-330 Industrial Conductivity Meter:

a) The instrument adopts a flow-through installation structure, with the main unit and electrodes integrated, without the need for additional transmitters
b) The instrument and external connection adopt a two-wire system (the working power supply and output signal adopt a common system), which is convenient and simple to connect, has a long transmission distance, and strong anti-interference ability
c) The instrument has a 4-20mA output (without isolated output). If the user needs isolated output, please select the isolation module (which is an optional accessory). The transmission output range can be freely set (within the measurement range)
d) Instrument display: 3 1/2LCD display, simultaneously displaying conductivity and temperature values
e) The instrument case has good waterproof performance, which can prevent water spray and dust intrusion
