Defender530+

The new 530+ replaces the Definer 220 MetLab series of calibrators effective January 16, 2017.

The 530 plus has the same flow rates as the Definer 220 from 5 cc to 30 liters to an accuracy of ±1% percent for readings standardized for temperature and pressure and ±0.75% in volumetric flow.

The MesaLabs Defender 530+, with the ability to take both volumetric and standardized readings, adds to the abiities of the popular Defender 510 and 520 line of DryCal primary flow calibrators. Automatic correction of readings for temperature and pressure, rather than merely recording of ambient conditions is essential in many applications.

The Defender 530+ provides users with a true primary flowcalibrator for industrial hygiene, environmental and laboratory applications.

Defender primary flow meters are 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.

The Defender 530+ 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 or warm-up times..

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 to the DryCal® Pro software.

The MesaLabs Defender – Overview

Accuracy 

• Proven percent of reading accuracy is supported by ISO 17025 accreditation by NVLAP of NIST

  •   Standardized: smL/min, L/min, cc/min, scf/min
•  Include up to one hundred readings in a group average
•  Take individual readings, continuous hands-free readings, or set to read in time intervals anywhere from one minute to sixty minutes between readings
•  Available in three models for application expansion. Use the
  •  Available in three models
  •  Defender 510 to calibrate personal air samplers and other volumetric instruments, or the
  •  Defender 520 “three-in-one” to calibrate volumetric instruments, record ambient temperature and pressure  conditions for your audit trail, or calibrate devices that read in mass flow.
  •  Defender 530+ for both volumetric flow readings or standarized readings, which correct for temperature and  pressure, or to calibrate devices that read in mass flow
