Graphtec America GL840-WV Data Logger 

The GL840 is a compact, lightweight, multi-CH, and multi-purpose data logger with a 7-inch color display.

20CH measurements are available with the standard terminal or Withstand high-voltage high-precision terminal, and 200CH measurements are available with the extension terminal base. In addition, when connecting various modules, the voltage, temperature and humidity as well as the acceleration, AC current, CO2, and illuminance / ultraviolet etc. can be measured.

The GL840 is compatible with the SD memory card. The high-capacity measurement data can be saved in the SD memory card that has various storage capacities.

For the PC interface, as USB and Ethernet is included as standard, system configuration according to use is possible. As the Ethernet function is equipped with both WEB server and FTP server functions, remote supervision and data transfer are also possible. In addition, when the wireless LAN and Petit LOGGER GL100-WL are combined by installing the wireless unit, the multipurpose remote measurement is also possible.

Features: 

  • WLAN capable using optional* WLAN Unit B-568 for remote monitoring and datalogging
  • 7 inch wide TFT color LCD screen
  • 3 types of power source: AC, DC*, rechargeable battery pack*
  • Extended memory capacity using SD cards
