Mesa Labs DC-LITE 1 - 40LPM
Mesa Labs DC-LITE 1 - 40LPM

The DryCal DC-Lite offers a primary flow standard that can be used for accurate calibration of all commercially available industrial hygiene and environmental air sampling pumps. Convenient features include AC/DC operation, a large alphanumeric LCD for flow rate, flow average with number of readings included in the average push-button read and auto-read of volumetric flow rate, automatic shut-off, a parallel printer port that interfaces with most PC-compatible printers - and no messy soap film. Three models of the DC-Lite Calibrator are available for rental: Model DCL 12K (10ml/min to 12LPM), Model DCL 20K (20ml/min to 20 LPM) and Model DCL 40K (1 to 40 LPM).

Mesa Labs Defender Primary Flow Meter
Mesa Labs Defender Primary Flow Meter

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.

Mesa Labs Definer 220
Mesa Labs Definer 220

The Definer 220 allows users to verify gas flow rates, in the field or in the lab, to an accuracy of ±1% percent of reading, including temperature and pressure compensation. Unlike thermal mass flow meters, the Definer 220′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, for traceable verifications of mass flow devices.

The Definer 220 represents the next generation of our Proven DryCal® Technology developed specifically for critical industrial and environmental applications. It provides the accuracy, customization and durability needed in today’s exacting, fast-paced workplace.

TSI 4046 / 4146 Sampling Pump Primary Calibrator
TSI 4046 / 4146 Sampling Pump Primary Calibrator

Personal samplin relies upon the accuracy of the data being generated which is where the TSI 4146 Cablibrator comes in. With a range of 0.01 to 20 l/min, the 4146 provides increased levels of confidence in your sampling. Compact and battery operated, the unit continuously displays real-time volumetric flow rate so adjustments can easily be made.

The 4146 measures flow rates of 0-20 l/min, whereas the 4046 measures flow rates of 0-300 l/min.
