Bios NVLAP Certification

The Bios Definer 110 is a compact indestructible EPA Flow Transfer Standard. The Definer 110 is small and lightweight, making it at home in the field, where rough handling is the norm. It is a direct replacement to fragile, glass-style orifice calibrators used in performing audits of PM2.5, PM10 and TEOM air samplers. It is compatible with most ambient airflow monitors.

The compact, durable orifice is designed to fit directly on an air sampler with a standard 1.25 inches OD inlet tube and the pressure drop across the orifice is measured with a digital manometer. Available in two flow ranges, the Definer 110 features an uncertainty of just 1% of flow reading within its rated flow range.

Each Definer 110 is calibrated in Bios' NVLAP - accredited flow calibration laboratory and the calibration numbers m and b are printed on the transfer standard.
