CEM DT-9883M Air Particle Counter + Gas Detector provides fast,easy and accurate readings for particle count. It can measure Mass Concentration, GAS Formaldehyde (HCHO), Carbon Dioxide (CO2), TVOC detection, Air Temperature & Relative Humidity and most surface temperature measurements.
KANE358INT is an ergonomically designed flue gas analyzer with direct measurement of carbon monoxide (CO) and carbon dioxide (CO2),with protection of the sensors. Based on measured CO and CO2 values it calculates O2, so you don't have to use an electrochemical oxygen measuring cell, which wears very quickly in standard flue gas analyzers. It also measures NO (required by Romanian regulations), temperature and pressure.
