The DULCOTEST CDE sensor for chlorine
®
dioxide (ClO ) is a diaphragm-covered two-
2
electrode sensor. The sensor consists of the
diaphragm cap and sensor shaft. The electro‐
lyte-filled diaphragm cap constitutes the meas‐
uring chamber. A non-porous diaphragm
located in the diaphragm cap allows the
chlorine dioxide soluble in the water to per‐
meate through. The electrodes on the sensor
