Description
Manufacturer: Pfeiffer
Model: TPR280
Condition: For Parts or Not Working. Comes in non-original packaging. This gauge is in fair cosmetic condition with minor scuffs from prior use on the case. The vacuum fitting looks clean but this item was not stored in a "clean" environment.
Cosmetic appearance may vary slightly from pictured unit(s).
Notes: This gauge is in at-least-PARTIAL working condition. We don't have a proper controller, so we used a bench power supply and voltmeter for testing. After warming up, the adjust button set the output to about 8.5VDC (normal). After sitting at a low pressure for a few minutes, the adjust button set the output to 1.5VDC (normal). As vacuum was released, the output voltage increased about the same amount on each of the units we have in stock, e.g. 3.5V at 1mTorr, 3.9V at 10mTorr, 4.6V at 100mTorr.
The thing we are not sure if it is proper, and the reason we offer this AS-IS, is the 8.5V reading when it got back up to atmospheric pressure seemed to drift a little (on the order of 0.1xV) but would hold fairly steady when the adjust button was pressed again. Also, at very low pressure, with a solid 1.5V reading, every few seconds the output voltage would spike over 2V for an instant and we are not sure why. No other testing was done.
No manuals, cords/cables, or additional items are included if not listed or shown.
