    *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.

    datalogging various input signals
    Analog signal input, Logic/Pulse and digital sensor port can be simultaneously connected to monitor a variety of measurements.

    Combine GL840 and GL100-WL

    You can expand your measurement variety by adding the sensors available on the GL100-WL unit.
    The measured value by GL100-WL will appear in a single file along with the measurement value from the GL840 main inputs. GL840 will now take in direct information from the GL100-WL units. GL840 supports up to five units of the GL100-WL.
    wi-fi remote triggering monitor instrument
    GL840 can use up to five units of GL100-WL as its remote sensor
