Description
Overview
GAOTek Infrared Methane Gas Detector can be a single or 4-gases detector for LEL, O2, H2S and CO, temperature and relative humidity detection function is also available. Gas concentration and history data can be displayed in the 2.4 in LCD HD color screen. Users can read all information immediately. It can also export history data to computer via USB port so that the users can view it in excel format or graph format.
Features
