Tested Works Pfeiffer TPR-280 Vacuum Gauge 24V DC Compact Pirani Pressure Transducer
Used see photos. Tested working, responds to pressure changes according to the manufacturer's voltage curve. See our test photos, we pulled rough vacuum on the gauge and it was sensitive towards this measurement. Not calibrated: if you need that done, there are other companies that are able to do this service for a fee. Does not include any of our testing apparatus (voltmeter, power supply, bellows, roughing pump) or anything besides the gauge itself and the DB-9 cable.
