There should be no air bubbles between the bulbs of the inner electrodes of the glass electrodes, and
if there are bubbles, the bubbles can escape easily.

2.4 Conductivity Sensor
2.4.1 Conductivity Sensor
Principle:
Conductivity indicates the electrical conductivity of a substance. The greater the conductivity, the greater
the conductivity and vice versa.
The conductivity sensor is a combination of two parallel plates. When it is placed in the solution to be
tested and a certain potential (usually a sinusoidal voltage) is applied across the plates, the interpolate
flow can be measured. The current passed. The conductivity of the water quality is calculated according
to the corresponding calculation formula.
The company has designed two conductivity sensors with different ranges: 1 μS/cm-2000 μS/cm (k=1)
and 100 μS/cm-100 mS/cm (k=10.0), users can follow their own The different requirements are selected.
The specific parameters can be found in the technical specifications below, where K represents the
electrode constant.
Conductivity probes not only test conductivity, but also convert to salinity and total dissolved solids.
