Industrial Hygiene
Since our beginnings, Bios has been at the forefront of providing the occupational health and safety market with accurate, convenient and reliable air sampler calibrations. In fact, Bios was founded in 1991 in order to supply industrial hygienists with the finest pump calibration equipment the world had to offer.
Our original Proven DryCal® Technology eliminated the need for liquid-filled instruments, bringing unparalleled simplicity to pump calibrations. Two product generations later, the occupational health and safety market is still our top priority – with the lessons learned from serving this fine market reflected in our latest generation of products.
The Bios Defender™ Series represents the latest in NIST-traceable, true primary calibrators. Each Defender is individually calibrated in our ISO 17025-, ANSI Z-540- and NIST Handbook 150-accredited gas flow calibration laboratory. At only 29 ounces, the rugged, sleek Defender travels easily, and exemplifies accuracy and simplicity. Just turn the Defender on, connect it to your pump and begin taking flow measurements. It’s that quick.
If it’s an enhanced audit trail that you need, the Defender 520 model in the series functions as a “three-in-one” primary standard – automatically and without the need for additional instrumentation. While you volumetrically calibrate your pumps, your Defender 520 model simultaneously records the temperature and pressure conditions of the calibration process for your audit trail.
Featuring ±1% of reading volumetric accuracy and a robust user-feature set, the Defender Series represents an evolution of Bios primary calibrators.
