The765-16B can be controlled via the bi-directional RS-232 or USB interface.
ETL has released the 765-16B portable barometric pressure measuring unit.
It can give barometric pressure readings of + or-0.08hPa or better in strong winds, all wind directions, pitch or tilt angles of up to 25 degrees, and in the presence of rain or freezing conditions.
The integral Digiquartz barometers have been extensively used in field transfer standards for ASOS and AWOS verification.
Barometric functions include altimeter setting, density altitude, field pressure, pressure altitude, station pressure and sea level pressure.
When it is switched on it is immediately possible to read the pressure values in any of the user-selectable engineering units.
Front panel selections include taring, resolution, sampling time, number of display units, engineering units, max/min readings, alarm points, and communication parameters.
The second line display can show an analogue pressure bar graph, sensor temperature, rate of pressure change, stored text or user-defined external text.
Free software is included and future upgrades are easily downloaded.
An internal logger can automatically store over 390,000 high-resolution data points.
The765-16B can be controlled via the bi-directional RS-232 or USB interface.
The unit is fully self contained in a rugged case and weighs only 3.86kg.
It can be powered by an included AC adapter or will run for 150 hours from rechargeable batteries.
The product has applications in aerospace, metrology, oceanography, meteorology, energy exploration, process control and laboratory instrumentation.
