When OSHA compliance and properly designed engineering controls are critical, an air sampler that provides constant flow or pressure is essential. Airborne monitoring methods are currently used around the world to establish the benchmark hazard from which risk to the worker can be predicted.

Air Sampling Pump Calibration methods should be validated before use to ensure they give results with accuracy appropriate to the measurement task.  NIOSH and OSHA both have validated air sampling and analytical methods. NIOSH Sampling and Analytical guide is an excellent source for this information. 

Personal air samplers control the flow of air to ensure a known volume of air is sampled.  Dust monitoring is accomplished using pre-weighed filters whereas vapor monitoring is done using media. The flow rate must be accurate so that the calculated concentrations are accurate. The pump maintains the airflow at the correct flow rate.

Personal sampling pumps must adhere to ISO 13137:2013, which sets limits for required flow stability, as well as maximum pulsation levels. The standard provides a comprehensive framework that specifies test methods to determine performance of air sampling pumps, and ensures environmental influences such as air pressure and temperature have a minimal effect on the accuracy of the sampled air, which in turn could affect sample results.

Why calibrate your air sampler?

  • Maintain steady state flow for accurate volumes
  • Assure that the air sampler works and stays functional throughout the entire testing period
  • Compliance with ISO 13137:2013
  • We are A2LA ISO 17025 Accredited
