The 7091 is a high-performance digital pressure gauge for vacuum to 40bar (600psi) measurement. The robust design means that it can be used in critical environments where it is necessary to measure with accuracy, reproducibility, long-term stability and protection against dust.

Accuracy is 0.2% of full scale, and features include easy to use controls and an RS-232 port situated on the rear of the unit. The 7091 can be used in various applications including field gauge calibration, safety valve testing, and pressure regulator checking.

It can accompany the 7090 handheld pressure pump, making a compact field pressure calbration kit, or be used with the 7193 pneumatic benchtop pump in the lab for reference calibration. It covers the full range of both pumps.
