Defender Series Calibrators

Overview

Turn the Defender on. Connect it to your pump. Take measurements. It’s that simple. Instantly calibrate your gas flow using Quick Start – there is no preparation involved, no messy soap bubble solutions. Defender’s many user-selectable options makes customizing your calibrations easy, giving you exactly what you need in the format you prefer. All you have to do is choose between the 510, the 520 or the 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 standardising Defender 530, give you the flexibility to do as much as you need while you work to defend lives.

For use with non-corrosive, non-condensing, non-combustible gases, less than 70% humidity.
