GL840 Data Logger

Quick Overview

The GL840 is a multi-channel stand alone data logger with isolated/universal inputs. The logger has 20 channels (expandable up to 200 channels) suitable for measuring voltage, current, thermocouples and RTD temperature inputs. The logger also expands to two different models for application specific use, plus a Wireless LAN allows the GL840 to be connected to the GL100 remote sensors or to a local network for remote access via a PC or smart devices. The GL840 comes with a 7" wide TFT colour LCD with waveform or digital options. The SD card slot allows for up to 32GB SDHC memory cards and the built-in USB port allows data transfer to PC or laptop and the Ethernet port allow for a wired connection to your network, or for direct computer connection, via web browser. The GL840 also allows FTP server functions and NTP synchronization with the Ethernet or WLAN ports.
