Update on my issues. After being in constant contact with MS a faulty “brush” was noticed on my original disc. First pic shows the disc and around 2 O’clock position note that there is nothing in that cavity. Now on the second pic note that there is a blue “brush” type of component present. That’s the brush that cleans the unit prior to sampling and measurement.
I also noticed that several very tiny starfish were “hiding” under the unit around the bottom part of the MS
See third pic.
So bottom line I think cleaning and inspecting the unit should be done at least on a weekly basis. Just my .02 cents.
And A plus for MS customer service
They have been very responsive to fixing my issues
Thanks MS
Hopefully unit keeps working as it did originally.
