Used but clean and in fair condition. This was pulled from a sputter deposition system that was decommissioned 2 years ago. While the meter was barely legible due to the painted numbers being worn off, we were able to make out 34,864 hours on it. The unit powered up and the helium gauge shows about 1800 kPa (270 PSI) on the system. We have no way to test the system further so the unit is being sold as-is.
