The ATS absolute 300 PSI pressure sensor reads positive pressure to 300 PSI while allowing negative pressure down to 14.69 Psi (-29.92Hg) to be read.

Don't have an ATS Scope to power pressure transducers... No problem! Consider an ATS Pressure Pro (PTR2000), Pressure Transducer Cable (PTR1080), and a Pressure Pro to BNC Cable (PTR1100) to allow your voltage measuring equipment to power the transducers
