It was new in the box. You can buy them for $169 on ebay with free shipping.
So to dredge this thread back up, I bought one of these and it arrived here today. To answer some questions: yes the end is potted(epoxyed) so the sensor is not replaceable. Well, it might be but my bet is that the subsequent calibration would be off.
For $115 I'm not going to complain. I'll try and get pictures up later.
