The Bios Difference

Sure, our products are primary, precise and convenient. But the biggest factor might just be the Bios Difference: A commitment to excellence. Our products are manufactured and tested in a laboratory environment recognized for excellence by a host of scientific, industrial and regulatory organizations in the United States and other global markets.

Our Butler, New Jersey facility is one of the world's most accurate gas flow measurement laboratories. Since 2004, we've been accredited to the calibration laboratory quality and proficiency standards set forth by ISO 17025, ANSI Z-540 and NIST Handbook 150, through the National Voluntary Laboratory Accreditation program (NVLAP) of the National Institute of Standards and Technology (NIST), the national lab of the United States.

We're pleased to state that our ISO Certificate Scope of Accreditation uncertainty is amazingly low, at only ±0.071% of reading for gas flow measurements from 5 to 50,000 scc per minute. With this degree of accuracy capability, you can be sure that your Proven DryCal® Technology product meets only the highest calibration quality during manufacturing, testing, calibration and Bios after-market service.
