I am very happy with the salinity tester. I use the PPT instead of salinity and that is my only beef. If the salinity were to read one more decimal out I would use the salinity. I do cover the reservoir every time I take a reading with small
ramekin I also calibrate the tester each time.
As
@Simon Cushing cushing would say, "when I go out for take away" I save the napkins and use the napkins instead of paper tower to clean the reservoir. The napkins do a much better job

That is the first time of have read about issue with the Milwaukee.
I am finding out that with any test to have consistency is to use clean/new tips, syringes, clean surfaces and the tests come out more consistent.
Thank you, the uppers and the desk is made with
