The TSI 4146 Pump Calibrator is a device manufactured by TSI Incorporated, a company known for producing precision instruments for measuring airflow, particulate matter, and other parameters in various applications including environmental monitoring, industrial hygiene, and occupational health and safety.

The TSI 4146 Pump Calibrator allows users to verify and adjust the flow rates of air sampling pumps to ensure they are operating within specified accuracy limits. This is typically done by comparing the flow rate measured by the pump against a reference standard, and adjusting the pump's flow rate if necessary.

The TSI 4146 primary calibrator continuously shows volumetric flow rate on its clear digital display, so it's easy to make pump adjustments, calibrations, and periodic flow checks in real time.
