Multi-range pressure standard has high
accuracy
This compact easily transportable unit can be used both on and off site and has applications in metrology, aerospace, hydrology, meteorology, oceanography, nuclear, laboratory and manufacturing
A new multi-range pressure standard for a wide variety of high accuracy pressure measurements for calibration, testing and transfer standard applications is now available from the ETL group Designated the 785 it incorporates one or two Digiquartz absolute or gauge pressure transducers, which are used exclusively as reference standards

New laboratory pressure transfer standard
The model 745 it is designed to give extremely accurate pressure measurements with a resolution of 0.0001% and 0.008% full scale accuracy
Multi-ranging allows each Digiquartz transducer to replace three separate transducers.
The two transducer model has six ranges, with push button selection between measurement modes, local configuration and customer set ups.
The easy to read display shows functions such as rate of change, pressure, maximum/ minimum pressure, average pressure deviations, and operator triggered instantaneously readings.
There is a choice of 25 different transducers with up to 75 active multi ranges available.
The range cover vacuum to 40,000psi (275Mpa), have a resolution to 1ppm (user-settable) and are fully compensated from -20 to +100C.
Communications to a host computer is via RS-232 or IEEE-488.
All transducers are protected by a self defense system to prevent over pressure damage as high as 1500psi, and may be dynamically compensated for atmospheric pressure changes during measurements.
