The Defender™ Series
New in 2010: Defender 530
Backed by Proven DryCal® Technology for fast, ±1% of reading calibrations of personal sampling pumps, the Defender 510, the enhanced Defender 520, and the standardizing Defender 530, giving you the flexibility to do as much as you need while you work to defend lives. The Defender Series has it all.
Defender 510 • Volumetric Primary Flow Standard
Defender 520 • Enhanced Volumetric Primary Flow Standard
Defender 530 • Standardized and Volumetric Primary Flow Standard
- a broad dynamic flow range
- choice of single, hands-free continuous, or user -specified "Burst" measurements
- the temperature and pressure conditions of the calibration process (520 model)
- standardizing readings (530 model)
- time intervals between measurements for checking personal sampling stability over a typical sampling period.
- a field-friendly, rugged and lightweight design featuring a large, illuminated liquid crystal display and intuitive menu navigation
- RoHS- and CE-compliance
