Description
Overview
GAOTek digital handheld environmental tester is mainly used for monitoring CO2 concentration and temperature and humidity in the environment, suitable for furnishing living rooms, classrooms and offices. It responds quickly, the measurement interval for temperature and humidity as well as carbon dioxide concentration is 5 seconds. The device has an alarm high limit function for the measurement data (bright red backlight), and the alarm value range can be set. It adds recording functions to the base. Users can press the button to set their recording interval and the file type generated. It saves and transfers files on U disk and produces txt or csv or xls or dlg format files (dlg format data can be analyzed with professional PC software). It also supports statistics of parameters such as overflow status, count and total overflow time of each channel.
