This is working and there is still ink in the printer. I don’t think it was used more than a few times as the main unit seems in excellent condition. Please see pictures

There is no original power cable but it works on 4AA batteries.

It is quite old and Hanna don’t seem to make it anymore however they do still sell the accessories.

I think it will need a new electrode because there are some small cracks in the tip of this one. They are still available from Hanna. I have taken some pictures of the various accessories available for this in the manual. Please see pictures.

I think this was around £1000 when new.

Questions welcome
