Ultrasonic Cleaning Element
For several weeks after starting the operation, check the ultrasonic cleaning element for
corrosion. If corroded, replace it with the type most suitable for the measurement solution,
selecting from among the element materials: SUS316 stainless steel, titanium and Hastelloy C.
If a corroded element is not replaced, the solution may enter the ultrasonic element and cause
problems. If this occurs, replace the cleaning element immediately.

(1) To remove a defective ultrasonic cleaning element, unscrew the cleaning element mounting
screw, so the cleaning element holder can be removed from the screw connector. Move
the cleaning element out until the connector appears, and disconnect the vibrator leadwire
connector from the holder side connector. See Figure 3.5.

(2) Check that there is no corrosion around the O-ring sealed surface. It is recommended that
the O-ring be replaced whenever the element cleaned.
(3) Mounting a new ultrasonic cleaning element. After attaching the connector, rotate the
cleaning element two to three turns and store the cable inside the holder. Secure the
cleaning element mounting screw. Check the cleaning element material by the marking
on the surface of the vibrator element; H for Hastelloy, T for titanium, none for SUS316
stainless steel.
