In-field and in-house calibration and metrology using portable transfer standards

Portable, NIST-traceable flow meters simplify calibration and validation of flow equipment at both state-of-the-art metrology labs and remote, outdoor sites.

  • Portable and durable. Built to be carried around, with an integrated display and battery lifetime of up to 18 hours and drop-resistance.
  • Versatile and accurate. Real-time measurements with NIST-traceable accuracy to ±0.5% of reading or ±0.1% of full scale for 98+ gases and 20 custom-defined mixtures.
  • Fast, multivariate data. Millisecond-response times immediately upon powering up, to display flow, pressure, and temperature readings in real-time, in your choice of engineering units.

Multivariate meters fully compensate for ambient conditions

Calibrating rotameters requires correcting them to specific standard or normal temperature and pressure conditions.

Alicat devices simultaneously measure mass flow, volumetric flow, temperature, and pressure in real time, so you can ensure your devices are calibrated to the correct operating conditions.

Calibration, validation, and verification

Validation ensures a system satisfies its stated functional intent, while verification ensures a process or equipment operates according to its stated operating specifications. Calibration ensures the measurement accuracy of an instrument meets a known standard.
