Mesa Laboratories

Mesa Laboratories products from TES provide practical solutions across ambient air monitoring, occupational hygiene, emissions studies, particulate matter assessment and sampling pump calibration. Whether you are building a monitoring programme, verifying a sampling train or maintaining measurement quality across multiple sites, Mesa equipment helps you work with confidence.

Environmental data is only as credible as the sampling method behind it. Mesa BGI instruments are designed for particulate and aerosol sampling applications where controlled flow, consistent collection and repeatable performance matter. Use ambient air samplers and particulate sampling accessories to support surveys of airborne particles, community exposure, site conditions and environmental compliance requirements.

Mesa BGI cyclones provide size-selective sampling options for personal exposure assessment and environmental studies. They are well suited to occupational and industrial hygiene programmes, helping teams collect respirable, thoracic or other fraction-specific samples when assessing airborne dust and particulates. For consultants managing complex field campaigns, robust and compatible sampling equipment can simplify deployment without compromising the quality of the results.

Accurate airflow calibration is essential when using air sampling pumps, flow-controlled instruments and gas measurement systems. Mesa Laboratories DryCal calibrators provide a reliable way to check and document gas and air flow performance before, during and after sampling work. This supports defensible data, consistent operating procedures and stronger quality assurance across environmental monitoring projects.

The DryCal range includes options for different flow ranges and accuracy requirements, allowing users to select a calibrator that fits their instrument fleet and application. From routine field verification to higher-precision flow measurement, these gas and airflow calibration tools help reduce uncertainty and keep sampling equipment operating as intended.
