Precision Digital Barometer
The Model DB-705 is a portable digital barometer possessing a combination of
handheld calculator size, digital display, high accuracy and wide choice of units, making it
ideal as a portable absolute pressure reference.
The DB-705 features a variety of pressure scales to enable the operator to display the atmospheric
pressure in a variety of units, including inHg, mmHg, mb, as the most widely used units in radiation
therapy. It also displays ambient temperature in ºC and ºF with one degree resolution.
The DB-705 operates on three AA alkaline batteries for 300 hours. The Auto-Off automatic timeout
prolongs battery life, but the feature can be disabled by holding the LEAK button while pressing the
ON-OFF button. The UNITS button sequentially selects up to 16 units of measurement. The
LEAK button sequentially selects maximum reading, minimum reading and initiates a 60-second countdown
for leak test. The TARE button sets a zero reading for use as reference.
The rugged, ABS molded case has been designed for hand-held use, either in field applications or for
use on the bench. The unit has an integral folding stand. A two-compartment soft carrying
pouch is included.
