The Model 765-16B is the best choice for accurate, reliable and stable barometric pressure measurements. The integral Digiquartz® Barometers have been extensively used in field transfer standards for ASOS and AWOS verification, meteorological measurement systems, altimeter setting indicators, air data test sets, and other critical applications such as GPS-Meteorology, infrasonic research, atmospheric wave and turbulence detection, and geophysical studies.
The Model 765-16B is portable, easy to use and fully self-contained in a rugged, compact case. Turn it on and immediately read barometric pressure in any desired 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.
Special Barometric Functions available on the second line display include Field Pressure, Station Pressure, Altimeter Setting, Sea-Level Pressure, Density Altitude, Pressure Altitude, Q Signals - QNH & QNE, and WMO Pressure Tendency Codes.
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 either continuously powered from its AC adapter or for up to 150 hours from the internal rechargeable battery.
