Bios Defender 500 Series Volumetric Primary Flow Standards

Bios Defender is the next generation DryCal dry flowmeter that provides users with a primary flow standard for industrial hygiene, environmental and laboratory applications. Available in two models for application expansion: use the Defender 510 to calibrate personal air samplers and other volumetric instruments, or the Bios Defender 520 "three-in-one" to calibrate volumetric instruments, record ambient temperature and pressure conditions for your audit trail, or calibrate devices that read in mass flow.
