DDG-33 Industrial Conductivity MeterDetailed product description：

Characteristics of DDG-33 Industrial Conductivity Meter:

Using single-chip microprocessor technology for automatic temperature coefficient compensation of aqueous solutions (including general electrolyte solutions and pure water), with precise data processing;  
The instrument can be automatically calibrated and the measurement range can be automatically converted, making it more convenient for users to use;   
The large screen LCD display can simultaneously display the conductivity and temperature of the tested solution, and the conductivity value has been automatically converted to the value at 25 ℃;   
It has an isolated current output of (4-20) mA, and its corresponding conductivity range is set by the user;   
Equipped with conductivity upper limit alarm function;   
The instrument has five working parameters: electrode constant, temperature coefficient, output upper limit, output lower limit, and alarm upper limit. Users can modify them according to their actual situation and have power-off protection function;   

Can be equipped with three types of conductivity cells:
2043-205B type, with a conductivity cell constant of 0.01/cm;
2043-405B type, with a conductivity cell constant of 0.1/cm;
2043-605B type, with a conductivity cell constant of 1/cm

Adopting a metal chassis with IP65 protection level.
