I have one of these machines that I assume was left in the basement of our building 10 years ago and never picked up by an inspector. I know this could be of some use to someone rather than sitting on a shelf where it has sat for 10+ years because no one in my office knew what it was. It was left in monitoring mode so there is not a carrying case or any cables as the manufacturer’s website mentions. There is a keyed on off switch on the front that is missing its key. There is a sticker on the back that says the machine was last sent to the manufacturer and calibrated on 6/12/02. I will provide pictures to anyone that is interested. Make an offer…I really just want to move this thing.
