New Videos Showing IAQ Pump Calibration Procedures Now Available Online

EMSL Analytical provides a wide assortment of indoor air quality (IAQ) and industrial hygiene sampling pumps, calibration equipment and supplies.


Cinnaminson, NJ, April 4, 2013
Last month, EMSL Analytical, Inc., released three new online videos describing how to perform primary calibration of various IAQ and industrial hygiene sampling pumps. The educational videos discussed primary calibration of high volume and low volume sampling pumps as well as popular portable pumps used to collect samples on Air-O-Cell® cassettes.
For indoor air quality and industrial hygiene professionals, sampling pumps are a critical tool used to collect air samples. They come in a wide variety of shapes and sizes, but regardless of the pump, for most sampling techniques to be performed correctly the pumps need to be calibrated utilizing a primary calibration technique.
“At EMSL, we get questions about how to perform primary calibration on sampling pumps all the time,” reported Jody Thomason, Director of Products/Corporate Purchasing at EMSL Analytical. “Although some sampling pumps have a built in rotameter, this typically only provides an approximation of the sampling pump’s flow rate. These pumps, with or without a rotameter, should be calibrated with a primary calibration tool to ensure their accuracy so that the sampling method being utilized is done correctly.  Watching a two minute video is a quick and user friendly way to see how primary calibration is done on these pumps. We hope these videos facilitate the process as they can be easily viewed from a smart phone or other device even at a jobsite.”
