Enhance audit trail by including temperature and pressure conditions during air sampler calibrations

530 model standardizes or corrects flow to ambient temperature and pressure conditions

*	Defender 520 model documents temperature and pressure for audit trail. Choose Defender 530 for flow-calibration corrected to these parameters

Three DEFENDER Models to Meet Your Applications

DEFENDER Primary Standard Calibrator 717 series

Defender 510: 1% accuracy volumetric calibration for personal air samplers and other volumetric instruments

Defender 520: with 1% volumetric accuracy, Defender 520 also records ambient temperature and pressure at time of calibration for enhanced audit trail

Defender 530: 1% accuracy volumetric and 1.2 % accuracy standardized calibration for environmental applications and calibrating mass flow meters and controllers

Laboratory and Defender Accuracy

Laboratory accuracy is certified by NIST through NVLAP and backed by ISO 17025 accreditation. Volumetric accuracy for the Defender 510, 520, and 530 models is 1% of reading. The Defender 530 also features a standardized accuracy of 1.2%.
