Up for sale is a YSI Pro20 Dissolved Oxygen Meter Instrument. This is for the tool only and does not include cable. We had several of these for our company that recently closed and this one I don’t think was every actually used as we had backups in the shop and the cable was taken from this one when one of our other cables and broke. Super clean, looks unused but listing as used since I can’t guarantee one of our techs never used it once or twice but there is no signs of use at all.
