The ETI 8140 series of Bayard Alpert ion gauges (also called a vacuum gauge, vacuum transducer, or hot cathode) feature a burnout-resistant iridium coated filament or two tungsten filaments for vacuum measurement. This vacuum gauge has a wide measurement range of 10-10 to 10-3 Torr and can be outgassed for extended life of the vacuum gauge and cleaning of hot cathode contamination. The dual filament vacuum gauge design allows you to use the second filament when the first filament burns out or becomes heavily contaminated in this vacuum transducer.
Looking for a cleanable, longer lasting solution? We suggest looking at our cold cathode technology, such as the 7FCS cold cathode vacuum gauge. This is a different vacuum gauge technology for ion gauge pressure measurement using a cold cathode vacuum transducer (instead of a hot cathode) which is less susceptible to contamination and is more easily cleaned when the vacuum gauge does become contaminated.
- Low cost vacuum gauge
- Outgassing and dual filaments for extended vacuum gauge lifetime
- Reliable hot cathode technology
- Contamination resistant vacuum transducer and resistant to inrushes of gas
- Excellent customer support for vacuum transducers
- Vacuum gauges designed and manufactured in the United States of America
