The Model 765 Transfer Standards provide the highest accuracy pressure measurements for portable field applications. The integral Digiquartz® transducers cover absolute and gauge pressure ranges up to 40000 psi (276 MPa).

The Model 765 is portable, easy to use, and fully self-contained in a rugged, compact case. Turn it on and immediately read the pressure values in any of nine userselectable engineering units. Front panel selections include taring, resolution, sampling time, number of display digits, engineering units, max-min readings, alarm points, and communication parameters. Choices for the second line display include an analog pressure bar graph, sensor temperature, rate of pressure change, stored text or user-defined external text.

An internal logger can automatically store over 390000 high-resolution data points. The Model 765 can also be controlled via the bi-directional RS-232 or USB interface with a new, improved command set. The unit is powered by AC Adapter (included), or by the internal, rechargeable 150 hour battery. Free software is included. Future upgrades are easily downloaded to the Model 765 firmware.

The Model 765 is the best choice for accurate, reliable, and stable pressure measurements.
