Compact 20 Channel Multi-Function Data Logger
The Graphtec GL840-M Compact 20 Channel Multi-Function Data Logger offers both DC Voltage up to 100V & Temperature measurements from thermocouples and RTD’s.
What we like: The GL840 Compact 20 Channel Multi-Function Data Logger can record large amounts of measurement data directly to the large internal memory or SD memory card, the USB drive mode function enables the internal memory and SD memory card to be recognized as an external drive by a PC for easy access to recorded data. The GL840 channel range can be extended from 20 to 200 channels. With the GL840’s high-resolution 7-inch TFT colour liquid crystal display you can clearly view recorded data in wave or digital formats or a combination of both for each of the channel’s settings.
