Compact Data Logger GL100 series

Limited stock

Best Choice for Easy and Quick Recording

GL100 is a data logger that can measure a variety of phenomena with simple settings because it automatically recognizes the sensor type by just connecting the sensor to it.
GL100 supports wireless LAN.
You can wirelessly connect to GL100 from a PC or smart device, check data at a distance from GL100, and remotely monitor via the Internet.
The application software comes standard for PCs and smart devices, so you can use it in different ways depending on your usage environment and purpose.

GL100 are using the Wireless LAN (WLAN) of the IEEEE802 standards. Area that can use it is limited by the Wireless Telegraphy Act in the region.
