Environmental Protection

Bios products have been used by environmental protection specialists for almost two decades to verify and calibrate various flow metering devices typically used in environmental monitoring equipment.

Bios products engineered with Proven DryCal Technology provide fast, primary results with little user-error or interpretation and only minimal training. Whether calibrating PM2.5 or PM10 air samplers or TEOM ambient particulate monitors, our products provide repeatable, accurate flow measurements day in and day out.

The Bios Definer™ 220 is a field-hardy primary flow meter that’s NIST traceable. Each Definer 220 is individually calibrated in our ISO 17025-, ANSI Z-540- and NIST Handbook 150-accredited gas flow calibration laboratory. At only 29 ounces, the Definer 220 is a handheld measurement device that includes a base volumetric uncertainty of just ±0.75% of reading. When set to automatically apply its integrated temperature and pressure sensors to its volumetric flow measurements, it offers a standardized accuracy of ±1% of reading, ideal for the calibration of environmental mass flow devices.

If you’re looking to further enhance your quality, the Bios Met Lab® Series provides the environmental specialist the ultimate in accuracy and traceability. Able to quickly calibrate all of your flow measurement devices, this line’s ML-500 and ML-800 products provide the repeatability and ease-of-use that you expect from the recognized world leader in primary gas flow measurement. Taking up only a small footprint on your lab bench and requiring only minimal training, the Bios Met Lab series will get you up and running in an instant – in no time at all, you’ll be free to concentrate on other aspects of your job. And with direct NIST-traceability, your air monitoring results are more defensible than ever.

Last but not least, the Bios gas flow calibration solution combines our award-winning technology with a number of complete solutions perfect for the environmental specialist. Turnkey FTS (flow transfer standard) calibrations are easy and fast, saving you costly, time-consuming annual calibrations. Our mass flow controller calibration solution allows you to automate calibration of the MFCs used in a various multi-gas calibrators, while rotameters and variable area flow meters are just as easily calibrated.
