Cleaning Devices

Optional item, if fitted.
There are two optional Cleaning Units available. Both allow routine cleaning of the
Sample Glass Tube. They are different in the way they are operated.
9.1

Manual Cleaning Unit (MCU)/ Automatic Cell Cleaning Device

The Automatic Cell Cleaning Device is driven pneumatically, while the Manual Cell
Cleaning Unit has to be operated by hand. The cleaning mechanism is identical: a wiper
moves through the Sample Glass Tube and removes deposits from the Sample Glass Tube
surface. This unit facilitates cleaning of the cell without the need of removing the Cell Cap.
Regular use of this device can reduce difficulties in operation of the monitor due simply
avoiding of the Sample Glass Tube and all the inconvenience this can cause.

9.1.1 Flow rate regulation on MCU, Auto Clean System

Flow rate is regulated by using a small O-Ring inside the cleaning device. There is a groove
for an O-Ring.

Cleaning Unit, manually operated
