MODEL 745

High Accuracy Pressure Standard
PERFORMANCE*
Parts-per-billion Resolution
0.008% Full Scale accuracy
RANGES
20 Absolute Pressure Ranges from:
0-15 psia (0.10 MPa) to 0-40,000 psia (276 MPa)
6 Gauge Pressure Ranges from:
0-15 psig (0.10 MPa) to 0-200 psig (1.38 MPa)

The Model 745 Portable Transfer Standards provide the highest
accuracy pressure measurements for laboratory and metrologicalapplications. Digiquartz® Transducers cover 26 absolute andgauge pressure ranges up to 40,000 psi (276 MPa) withunsurpassed accuracy, reliability and stability. The simple, intuitive
front-panel user interface and versatile functionality with the rearpanel RS-232 computer interface make the Model 745 the best
choice for high performance pressure calibrations.

The Model 745 is portable, easy to use, and fully self-contained ina compact case. Turn it on and immediately read the pressure
values in any of nine different user-selectable engineering units. Allpressure readings are fully temperature compensated andlinearized. Tare functions, pressure units, temperature units,resolution, sampling time, number of display digits, communication
settings, baud rates, sensor address, and passwords can beselected via the front panel menu system. The choices for secondline display include an analog pressure bar graph, sensor
temperature, rate of pressure change, and stored text or external
text. The unit can also be controlled via the bi-directional RS-232
interface. Free software is included to read and log data via theRS-232 port.

The Model 765 Transfer Standards provide the highest
accuracy pressure measurements for portable field
applications. The integral Digiquartz® Transducers
cover absolute pressure ranges up to 40,000 psi (276MPa) and gauge pressure ranges up to 200 psig (1.38MPa).
The Model 765 is portable, easy to use, and fully selfcontained in a rugged, compact case. Turn it on andimmediately read the pressure values in any of nineuser-selectable engineering units. Front panel
selections include taring, resolution, sampling time,number of display digits, engineering units, max-minreadings, alarm points, and communication parameters.
Choices for the second line display include an analogpressure bar graph, sensor temperature, rate ofpressure change, stored text or user-defined externaltext.
An internal logger can automatically store over 390,000
high-resolution data points. The Model 765 can also becontrolled via the bi-directional RS-232 or USB
interface. The unit is powered by an AC Adapter(included), or by the internal, rechargeable 150 hourbattery. Free configuration and logging software isincluded.
The Model 765 is the best choice for accurate, reliable,
and stable pressure measurements.
