The Defender 530+ allows users to verify gas flow rates in the field or in the lab to an accuracy of ±1% percent for readings standardized for temperature and pressure and ±0.75% in the volumetric flow mode. Available with flow rates from 5 cc to 30 liters. 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, rather than just recording the values, for traceable verifications of mass flow devices.

Defender 530+ Calibrator - Flexible Ways of Working

No matter your application, the portable Defender 530+ is ready to go to work for you, because it’s a true volumetric standard based on the principle of positive displacement.

The Defender 530+ provides immediate indication of the actual gas flow rate, accurately and independently of the gas type. It also includes integrated temperature sensors and pressure transducers in the flow stream, so you can compensate for standard conditions - allowing traceable verifications of mass flow devices. A versatile, push-button flow meter, the Defender 530+ is also a primary flow standard, enabling you to accurately calibrate a variety of instrumentation.
