GE Druck DPI-740 Precision Barometer
The Druck 740 is a portable battery powered precision barometer, providing outstanding capabilities in a handheld package. The fundamental sensor technology employed within this instrument is the Druck Resonant Pressure Transducer (RPT). This vibrating element sensor not only provides accuracies of +/-0.005 inHg but equally important has a calibration stability of better than 100 ppm per year. This instrument can confidently be used in both laboratory and field applications as a first-class barometric reference device, with the recommended recalibration period being one year. A variety of pressure scales is available to enable the operator to display the atmospheric pressure in any desired units or in height equivalent units for altimetry and surveying applications. With the serial RS 232 interface, it is possible to utilize the DPI 740 data as input parameters to computer systems or simply print out the displayed values. The DPI 740 ABS molded case has been designed for hand-held use, either in field applications, or for use on the bench with its integral folding stand.
