Abstract
Portable dynamic set-up is designed for the calibration of gas sensors and gas analytical instruments "in situ", that is in the place, where these sensors or instruments are installed (laboratory, factory, ecological monitoring system etc.). The set up uses ambient air for the preparation of calibration gas mixture and is equipped with air pump, catalytic filter removing undesirable impurities from ambient air, and diffusion source of target gas. Using this setup, calibration gas mixture with compounds, which could be liquefied at normal temperature (NH3, NO2, Cl2, HCl, formaldehyde, …), are prepared with precision of 1 - 4 %. The set-up powered by rechargeable battery enables the operation during at least 4 hours.
