美國SKC Drycal dc-lite校準(zhǔn)器外文參考：
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.
