▶ 📝 Notes
* Measuring hight above building: The measurement container extends about 1.5 m higher than the measurement height. However, the inlet is horizontally about 2.5 m away from the container wall. * Distance from condensables inlet: 40 m / 5 m - distance from the CI-APi-TOF located at the main site (ground level) / CI-APi-TOF at the Tower
