DryCal Defender Series

DryCal Defender Series

DryCal Defender Series

Accurate, Reliable & Portable Primary Calibrators for Fast Calibration of Air Sampling Pumps

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, give you the flexibility to do as much as you need while you work to defend lives. The Defender Series has it all.

Our laboratory is a fully accredited ISO-17025 facility with a 0.08% Scope of Accreditation for gas flow by NVLAP of NIST.

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