GL 7000

Modula Type Data Acquisition Platform

Modules allow wide range of measurements
  • Measurements for different applications can be added to the module. It is also possible to mix measurements by adding different types of modules.
Extending modules
  • Up to 10 modules can be attached to one main unit
  • Maintains the maximum sampling speed even when the number of input modules are incarcerated.
  • A wide variety of measurements can be supported by the input module. Up to 10 modules can be attached for multi-channel measurements, with up to 112 channels on one GL7000.
Touch panel system
  • The touch panel makes setting the conditions intuitive, and it can also be operated using the cursor keys similar to the GL series.
Supports multiple storage
  • Supports multiple types of storage and network function according to the condition of the measurement.
