!!
The DC-Lite is not rated intrinsically safe and is not for use with explosive
gasses or for use in explosive environments.
!!
The DC-Lite is not designed for pressurization above 0.35 bar (5 PSI) or for
gas flows above the rated specifications of the flow cell in use. Please consult the
product specification on the inside front cover of this manual for acceptable gas
flow ranges, or visit our website at www.drycal.com for the most current
product specifications.
!!
For use with clean laboratory air or other inert, non-corrosive gasses only.
4.0 General Description
The DryCal DC-Lite is a field-portable primary flow calibrator used for industrial
hygiene, environmental, and laboratory flow measurement applications. Using
patented, near-frictionless dry piston technology, it combines the accuracy of a
primary standard with speed and convenience.
The DC-Lite can be used to measure gas flow for either a vacuum flow
source (connected to the outlet port) or a pressure flow source (connected to the
inlet port).
Compact and housed in a small, sturdy case, the DC-Lite offers user-conveniences
such as simple push-button operation, auto-read, measurement averages, battery
level indicator, 5-minute auto shut-off, and a parallel printer port.
