Description
Overview
GAOTek handheld ammonia gas detector is the basic model of portable instruments. It can be a single gas detector or 4 gases detector for LEL, O2, H2S and CO, and temperature and relative humidity detection function is also available if you need. Gas concentrations and history data can be displayed in the 2.4 inches LCD HD colour screen, user can read all information at a glance. It can also export history data to computer via USB port so that the users can view in a EXCEL format or graph format.
