The airQrate is a flexible, modular multi-gas calibrator designed to generate accurate zero and span calibration gases for air quality analyzers measuring pollutants such as ozone, NOx, SO₂ and CO. It enables fully aed multi-point calibrations without the need for multiple gas cylinders, reducing operational costs and simplifying setup.

With integrated data logging, remote browser control and a compact design, airQrate saves time, improves calibration reliability and is ideal for both laboratory use and on-site air quality monitoring stations.
