AIR SAMPLING EQUIPMENT
Digital Flow Meters

AIR SAMPLING EQUIPMENT – DIGITAL FLOW METERS
The Defender 520 the go to flow meter for occupational hygiene measurements of volumetric gas flow with an accuracy of +/- 1% of reading and measures gas flow temperature and pressure. Both instruments use proven DryCal® technology to measure volumetric gas flow.
Measure volumetric flow, standardised flow, which correct for temperature and pressure, or calibrate devices that read in mass flow. 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.
The Defender calibrator is easy to use. Turn it on. Connect it to a sampling pump. And 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.
Pneumatic Test Kit
Pneumatic Test Kit, for testing flow compensation in personal sample pumps, 1 to 5 L/min rotameter, 0 to 80 inches magnehelic pressure gauge.


Laboratory Film Flowmeter Kit
Laboratory Film Flowmeter Kit with precision 300 to 5000-ml glass buret, soap film solution, adapter for vacuum or pressure, aluminum tripod stand, and instructions.
Low Flow Sampling Pumps
With its wide flow range of 5 to 5000 ml/min, the XR5000 is the best choice for most air sampling applications, it a favourite for airborne fibre monitoring in accordance with the Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres 2nd Edition. For greater worker acceptance, the XR5000 is lightweight and portable. The XR5000 air sampling pump is outfitted with a rugged impact-resistant RFI/EMI-shielded case with removable battery pack. Shielding protects the air flow from outside interference ensuring accurate air volumes and data validity; covers protect battery charging jack and computer interface port; CE-approved.
