RS485 Two-Electrode Online Conductivity Sensor For Industry Sewage
Digital 2 Electrode Conductivity Sensor DEC790 is a sensor for
measuring the conductivity of solutions.
The digital 2-electrode conductivity sensor can be directly
connected with digital equipment and control systems through
digital output of measurement results to achieve high-precision
data transmission and processing.
The sensor measures with two electrodes, usually a measuring
electrode and a reference electrode. This structure can eliminate
external interference and can provide higher-precision conductivity
measurement results.
Automatic temperature compensation, this sensor can be applied to a
wide range of conductivity measurement, has a fast response time,
can quickly respond to changes in solution conductivity, and is
suitable for real-time monitoring and control applications.
High precision and digital output make it easy to integrate with
modern automation systems, reducing the complexity of manual
operations and data processing, using digital design and
high-quality materials, with long service life and good stability,
reducing maintenance and the frequency of replacement. Making it
one of the sensors of choice for many conductivity measurement
applications.
