This high purity water pH sensor is specially designed
for continuous in-stream pH measurement of pure and
ultra-pure water.
It uses a reference electrode very similar to the
measuring electrode (combined concentric electrode)
in order to minimise the impedance under which the
measurement is carried out.
It is made of 316L stainless steel, which protects the
measurements from electrostatic (evacuation of the
charges resulting from the passage of the low
conductivity liquid) and magnetic disturbances.
The circulation chamber was designed without a
retention zone in order to avoid any disturbance of the
measurement
accumulation of air bubbles or insoluble deposits (iron
oxide, residues salted out by the resins).
