Tempe, Ariz.— PG7000 Differential mode is a hardware- and software-based solution for covering differential pressures with a piston gage. A piston gage is combined with a precision digital pressure transducer to cover positive and negative differential pressures near zero at static pressures from 2 psia, to just above atmospheric.

Tempe, Ariz.— PG7000 Differential mode is a hardware- and software-based solution for covering differential pressures with a piston gage. A piston gage is combined with a precision digital pressure transducer to cover positive and negative differential pressures near zero at static pressures from 2 psia, to just above atmospheric. Integrated piston gage software and specially developed hardware accessories support the process, reducing operator influence on calibration results. DH Instruments
