NEW MesaLabs Bios Defender 530+ Plus
Standardized & Volumetric Flow Measurement
Primary Standard Air Flow Calibrator
Air Flow Calibrator with DryCal^® Technology

The 530+ replaced the Definer 220 MetLab series of calibrators in January 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 flow calibrator 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
• Integrated temperature sensors and pressure transducers placed directly in the flow stream for optimum standardized results.

•  Housed in a molded case with rubber handgrips for a better feel and a sleeker, more contemporary look
•  Large illuminated flow cell viewing window
•  Navigation menu and a large, illuminated graphical display with zoom feature
•  Rated for extreme cold operation, down to -20 ºC
•  RoHS (Restriction of Hazardous Substances) compliant for Europe
•  Automatic Shutoff

•  Choose between flow units
  • – Volumetric: mL/min, L/min, cc/min, or cf/min
  •   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

The Defender 510 and 520, Defender 530 and the Met Lab Definer 220 calibrators can use the new DryCal Pro software for bullet-proof transfer of volumetric and standardized flow data and have automatic recording and graphing of flow measurements.

These records can also be easily opened in a variety of off-the-shelf database applications, including Microsoft Excel or Access.
