ARA FTS Flow Calibrator


Measure volumetric air flow, barometric pressure, and ambient temperature in conjunction with the ARA N-FRM Sampler.


The FTS Calibrator accurately measures volumetric air flow, barometric pressure, and ambient temperature. 

Using three Venturi Flow Devices (VFD), the FTS Calibrator efficiently calibrates and audits ambient air samplers and industrial hygiene samplers. Its easy-to-use interface allows for simple operation. Air flow is calculated and displayed at both ""ambient"" and “standard” conditions of pressure and temperature. NIST traceable flow accuracy.
