I have a Neptune Trident NP (no reagents) for sale). This unit is around 6-7 months old. I've found that my NP measurements are fairly stable and a monthly test with my Hanna checkers is all I need. I took it out of service using the automated task so it should be ready to be reconnected to an Apex and put into service with no issues. Please note that the photos show reagent bottles in the apex but they are empty (and rinsed out). There are no reagents included with this sale. This unit without reagents sells for $669 new - I'll take $450 shipped anywhere in the CUSA.
