The pods measure NO, NO², NO^x, O³, CO, SO² and %RH, temperature and atmospheric pressure. Gases are measured using the latest generation of electrochemical sensors, which allow compensation for environmental factors and sensitivity to 5ppb. The system combines a robust hardware platform with the latest sensor technology and GPRS communication, cloud-based data processing and secure online access. The 2 pods are part of the Mobile Lab for Environmental measurements.
