pH / ORP Analyzer
4.2.3. Differential Sensor
Differential Sensor features an Active Electrode (pH), a Reference Electrode (Ref.),
a built-in Grounding Electrode to eliminate noise / disturbance and a built-in
Temperature Electrode for temperature compensation. The sensor also features a
built-in pre-amplifier which enables an installation exceeding 25m cable length
while maintaining excellent reading accuracy and consistency. The short pin is
required in this setup.
