Enhance your Audit Trail with the Defender 520
Protecting lives is important work. If an enhanced audit trail is what you need to get the job done right, the Defender 520 "three in one" primary standard gives it to you - automatically and without the need for additional instrumentation. While you calibrate your pumps, Defender 520 simultaneously records the temperature and pressure conditions of the calibration process - convenient, and defensible.
Optimizer Software Suite
Take the calibration process one step further and use Defender's Windows based Bios Optimizer 110 software (included). Bios Optimizer 110 establishes communication with your Defender, downloads calibration data in real time, display and graphs it on your PC's screen and stores it to a text file - no configuration necessary. Even better, upgrade to Bios Optimizer 120 for ultimate audit trail - a comprehensive pump database, complete with pump profiles, printable pre and post calibration reports, search features and more.
Flexible Ways of Working
Calibrate pumps under suction when sampling through a filter or sorbent tube, or take measurements under positive pressure when calibrating pumps to fill gas sample bags for collecting gas and vapor samples. Take measurements one at a time or take continuous measurements using the hands free Continuous and Burst modes including user selectable group averaging from 1 to 100 measurements. To track pump stability over time, set the time between measurements from 1 to 60 minutes and log your readings into your PC over a typical run period. Or, decide how to view your data - select your preferred measurement units and use the handy zoom feature (Defender 520 only) to display the size and detail that's right for you.
