MILEVA 33 is the latest model by SENSIA for Optical Gas Imaging of micro-leaks of hydrocarbon gases (HxCx). A spectrally optimized cooled detector of 640 x 512 pixels has improved the minimal detection leak rate (MDLR better than 0.35 g/h of CH4). The MILEVA 33 is compatible with Redlook Lite, increasing the functionality and simplicity of the device, merging both SMART LDAR and Method 21 in a smart and digital way.
