Backed by Proven DryCal® Technology for fast,1% of reading calibrations of personal sampling pumps,the Defender 510 and Defender 520 give you the flexibility needed to enable you to do your work – defending lives. The Defender Series has it all.
Mesa Labs 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.
The Defender 530+ allows users to verify gas flow rates in the field or in the lab to a volumetric accuracy of .75% of reading, including temperature and pressure compensation. Unlike thermal mass flow meters, the Defender 530+’s positive displacement technology provides immediate indication of actual volumetric gas flow rate – accurately and independently of gas type. Integrated temperature and pressure sensors in the flow stream allow users to automatically standardize volumetric flow readings to standard conditions, for traceable verifications of mass flow devices.
