9065 Luminescent Dissolved Oxygen Analyzer

4.

Fit the O-ring to the new coating holder.

F
i

5.

Apply a drop of Loctite 572 to the inside of the
coating holder’s screw thread. This is to stop the
coating holder from shaking loose.

Make sure no

glue gets on the pink side!

6.

Screw the coating holder back on to the sensor, return the sensor to the mounting plate, and
calibrate the sensor.

Warning!

Never unscrew or loose the temperature sensor.
Unscrewing the temperature sensor will void the warranty.

Apply Loctite 572
