Calibration for accuracy

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.

Applications and use cases

Calibration and accuracy specifications for Alicat devices

Each device calibrated by Alicat^® comes with a NIST-traceable Certificate of Calibration. This guarantees that the device’s calibration can be traced back to primary SI standards such as mass and pressure. As a result, an Alicat device will output mass flow rates that fall within the same accuracy range as measurements obtained by any other similar NIST-traceable unit with an identical accuracy specification.

Gas sensor calibration - Things to bear in mind

Whether developing a gas sensor and testing its sensitivity and repeatability, or calibrating a sensor for quality compliance, you likely will need a traceable reference test gas. Make your reference gas using a FusionFlow™ gas mixer, and calibrate your analyzers with a portable battery-powered meter.
