Specifications

Make your life healthier and more comfortable.


Description

YEM-40B/40BL is mainly used for environmental carbon dioxide concentration and temperature and humidity monitoring, suitable for home furnishing, classrooms and office places.


YEM-40B response is fast, the temperature and humidity and carbon dioxide concentration measurement interval are 5 seconds. The instrument has the measurement data over-limit alarm function (bright red backlight), and the alarm value range can be set.


YEM-40BL adds recording functionality to the YEM-40B base.Users can press the key to set their recording interval and the generated file type. YEM-40BL stores and transfers files in a U disk, generating txt/csv/xls/dlg format files (data in dlg format files can be analyzed with professional PC-side software). YEM-40BL also supports the statistics of parameters such as the overrun state, number and total overrun time of each channel.
