PRODUCT DESCRIPTION
The BIOS Defender is a high accuracy primary liquid-free gas flow calibration standard that doesnﾒt require the use of bubbles or other liquids. Pushbutton operation and an intuitive user interface make taking flow measurements quick and easy. All you do is set your engineering unit, your temperature setting, select continuous or burst measurement, connect your flow source, and start taking your readings. It's ideal for industrial hygiene, environmental, and laboratory applications. Use the 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.
