7091 Digital Pressure Gauge
• -1bar vacuum to 40bar (-15 to 600psi)
• Accuracy 0.2% of full scale
• Easy to read display with 5 digit resolution
• Analogue dial for % pressure indication
• Unique self-protection capability technology
• 3 times per second measure speed
• Suitable for field calibration applications
• Ideal for use with the 7090 and 7193 pumps
DESCRIPTION

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.
