GRAPHTEC Multi-channel Data Logger GL840-M
Isolated/Universal input, Standalone Multi-Channel Data logger
20 Channels in standard configuration. Expandable to 200 Channels
GL840 has two line-ups that are “multi-inputs model”, suitable for temperature measurement with multiple channels, and the “withstand-voltage model”, suitable for stacked high voltage battery application, or high-precision temperature measurement.
Supports three types of input formats and the analog signal input port can be expanded from the standard 20 channels to a maximum of 200 channels. It measures a variety of phenomena.
The optional wireless LAN unit enables wireless measurement, remote monitoring and measurement, and expanding the measurement range.

GRAPHTEC Isolated simultaneous 8-channel data logger midi LOGGER GL980
Multifunction input on 8 isolated channels including true-RMS value measurement
GL980 is a high-voltage isolated 8-channel data logger that supports a 500V range, RMS measurement capability, all channels isolated simultaneously at 1MS/s, and high-speed sampling. It can be used for machine performance and durability testing.
Inside, 4MW/ch internal RAM and 8GB internal flash memory. Outside, SD memory card and USB memory storage media. It is possible to record high-speed and long time. The DP-581H thermal printer can be connected and data can be handed over on the spot. It prevents data falsification and prevents data tampering.
GRAPHTEC High-speed High-Voltage Isolated 4 channel Data Logger midi LOGGER HV GL2000
High-speed 1 MS/s simultaneous sampling with voltage and temperature measurement
GL2000 is a high-voltage isolated 4-channel data logger that corresponds to CAT III 600 V and up to 600 V rms measurement, all channels isolated simultaneously at 1 MS/s and high-speed sampling. It can measure factory equipment and high voltage measurements.
The DP-581H thermal printer can be connected and data can be handed over on the spot. It prevents data falsification and prevents data tampering.
Inside, 4MW/ch internal RAM and 8GB internal flash memory. Outside, SD memory card and USB memory storage media according to the sampling interval and situation.
GRAPHTEC Monitorless Data Logger GLT400
Multi-use & Multi-function Input Data Logger
20 Channels in standard configuration. Expandable to 200 Channels
GLT400 is a multi-use data logger that can be used as an extension unit and a stand-alone measurement such as utilization at research and development, newly expanding the sector to production engineering and production, incorporation into control panels and devices, data acquisition from PLCs via Modbus/TCP, and as PC loggers.
Three types of analog input terminals are available in the lineup, which can be selected due to the input type, and can be expanded from the standard 20 channels to a maximum of 200 channels. We can provide a document on how to connect to PLCs and other devices using Modbus/TCP
GRAPHTEC Modular Data Acquisition Platform GL7000
GL7000 can be used for a wide range of applications in various measurement scenarios by expanding the module. The removable touch panel display module allows both “stand-alone” and “system-embedded” applications. Also, by attaching a display module, various settings, and measurements can be done without a PC.
“GL-Connection”, the integrated waveform viewer for the GL series is included as a standard accessory.
It can manage various information such as “recording data” and “waveform data playback stored in the GL7000 main unit or PC”.
Compact Data Logger GL100 series
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.
