FTS Flow Calibrator

PN 400-000

  • The FTS Calibrator accurately measures volumetric air flow, barometric pressure, and ambient temperature. Using a venturi-based flow element, the FTS Calibrator efficiently calibrates and audits ambient air samplers and industrial hygiene samplers. Its easy-to-use interface allows for simple programming and operation. Air flow is calculated and displayed at both ambient conditions and “standard” conditions of pressure and temperature.


  • NEW! The newest version of the FTS Calibrator is now equipped with bluetooth capability to connect directly to your smart phone or tablet. This handy feature will limit the amount of time spent climbing up and down ladders, to achieve efficient and accurate site calibrations.
