The Recordum airQrate is a modular, high-precision multi‑gas calibration system designed for both laboratory and field use. Built on a Linux-based platform, it combines browser-based control with an intuitive touchscreen interface. Ideal for calibration of ambient air quality instruments—including those used for NOₓ, O₃, CO, and SO₂—airQrate offers automated multi-point calibration, internal zero-air generation, dilution modules, and optional ozone or permeation modules. It also provides built-in data logging and report generation, making it a robust solution for environmental monitoring and compliance applications.
