Bios DC-1 DryCal Flow Calibrator - Primary Air Flow Meter
The DryCal is a field-portable true primary air flow calibrator. Using near-frictionless piston technology, it combines the accuracy of a primary standard
with unequaled speed and
convenience.
The Bios DC-1 Dry Cal consists of two primary sections. The base contains the electronics
and computer, while the flow cell performs the actual physical measurements. The
base has an opening on its upper surface into which the flow cell is installed. The front
of the base is angled for easy reading of the LCD display and includes a Power
On/Off switch and Charge LED indicator. Below these are push-button
switches.
Flow readings are obtained with the push of a button. The DryCal can be set to
take flow readings automatically or manually. A charging jack located on the left side
of the base is for insertion of the battery charger's barrel plug and a built-in
standard parallel printer port for hardcopy printing of flow readings is located on the
rear panel. The Bios DC-1 DryCal interfaces with most IBM compatible printers.
