Features
The following features are available on all RUSKA 7350s.
Mercury-Free
All components in the RUSKA 7350 are mercury-free.
NIST Traceability
All RUSKA 7350s are calibrated per ANSI/NCSL Z-540-1-1994 using RUSKA
deadweight gauges that are directly traceable to the National Institute of Standards and
Technology (NIST). All instruments are provided with a NVLAP accredited calibration
certificate.
Power Supply
The RUSKA 7350s are either 100 – 120VAC, 1PH, 50/60 HZ or 220 – 240VAC, 1PH,
50/60 HZ.
Measure While Control
The RUSKA 7350 simultaneously digitally displays the commanded pressure, the actual
pressure, and the difference between the two. A bar graph indicates how close the actual
pressure is to the commanded pressure, as well as how close the commanded pressure is
to the RUSKA 7350’s full scale pressure.
Friendly Display
The RUSKA 7350’s color active matrix TFT display combines a bright, low-glare
readout with a wide viewing angle. During normal operation, the measured pressure is
easily visible from a distance of 10 feet (3 meters).
Adjustable Pressure Display
The pressure display may be adjusted to show one decimal greater than or less than the
default resolution.
