From a shop close out

The PCA powers up and goes through menu, etc, - you have to have probes connected or you'll get an error (googled this)

This is as far as I tested this set up

Not sure how it works

The printer powers up and appears to take an Ethernet style cord - all it does it power up - not sure how to operate it

The probe is in good condition and includes a bag of extra filters(?)

There is an O2 sensor some tubing, a true spot pump, and hose connectors

A unit calibration letter dated 2009

A hard case to put everything in
