GL840 is Graphtec’s newest Multichannel Standalone Data Logger
GL840 Comes Standard with:
*Optional accessories not included
***All units include standard manufacturer’s certificate for factory calibration***
Two separate GL840 models available
Max Sampling Interval of up to 10ms
GL840 series carries two SD memory card slots
SDHC up to 32 GB supported. Captured data can be stored in GBD (Graphtec Binary Data) or CSV file format.
Capturing time* (when all 20 analog channels are being used with Logic/Pulse inputs turned off).
*Figures are approximate. File size of captured data is 2GB in GBD or CSV file format on this chart. Sampling interval is limited by the number of channels in use (10ms:1ch, 50ms:5ch, 100ms:10ch). Limited sampling speed is available when digital sensors and GL100-WL are used as a remote monitoring device.
