The Bios name is synonymous with primary gas flow measurement. And while our durable, flexible AirPro® sampling line remains in use by countless customers around the world, it was our original, field-portable primary gas flow measurement standard that laid the foundation for our future.
The world’s first "dry” calibrator – or, DryCal® – was born in 1991. Introducing our patented technology, our DryCal DC-1 and DC-2 models soon became the favorite of industrial hygiene professionals. PEMCO is a distributor of Bios products in the Northeast U.S. markets.
Our reliable DryCal technology remains a liquid-free, entirely portable volumetric piston proven design – which means it doesn't rely on messy liquid soap solutions to create bubbles that measure flow, oil and mercury seals used by enormous bell provers and hazardous mercury systems, or non-primary thermal flow elements that are more susceptible to errors from drift or environmental conditions.
With its simple push-button operation, liquid-free nature and fast measurements, primary DryCal technology – which we now refer to as Proven DryCal® Technology – provides the basis for an ever-expanding array of products and solutions, with the flow ranges and accuracies that meet the individual demands of wider market segments. Today’s Bios portfolio includes the Defender™ Series of primary gas flow standards, the Definer™220 primary flow meter, the Met Lab® Series of high-precision primary piston provers and the Integrator™ 110 command, control and readout device – not to mention our Bios Gas Flow Calibration Solution, which gives you everything you need to fully automate your internal calibrations.
