Mesa Labs Defender 510 and Defender 520 are the next generation of the DryCal® DC-Lite and DryCal® DC-2 flow Calibrators.
Everything you trusted about Mesa Labs DryCal® technology in the DC-Lite and DC-2 digital flowmeters is available in the Defender 510, 520 & 530 calibrators that make it easier than ever to calibrate air sampling pumps. Measure volumetric flow, standarized flow, which correct for temperature and pressure, or calibrate devices that read in mass flow.
Mesa Labs Defenders are true primary flow meters designed to provide light weight ultra-compact size, incorporating the industry leading DryCal technology. Building on the patented DryCal near-frictionless piston technology, the Defender 500 series incorporates features to make it immune to flow source pulsation without the need for in-line dampers.
Like all Mesa Labs calibrators, the Defender calibrator is easy to use. Turn it on. Connect it to a sampling pump. Start taking readings. It's as simple as that. Calibrations within a minute with no messy soap bubble solutions to wait on or clean up after.
The Defender 510, 520 and 530 can take hands-free continuous readings while quickly and accurately setting the flow rate on air sampling pumps or other instruments. The Defender calibrators connect to any PC and pre- and post-calibration data can be downloaded with the included Optimizer Collect Light software.
