You are bidding on an EX-BMR (Bureau of Mineral Resources) TEMPERATURE AND SALINITY METER.
This unit was used for water quality sampling trips.
It is a YSI MODEL 33 - S-C-T METER.
I am not sure if it still works.
It has been sitting on my garage shelf for about 10 years (some of the solution has crystallised a bit)
I am happy to answer any questions about this unit to the best of my ability
