Key Features

Input

Adoption of pluggable M3 screw type input terminal facilitates wiring
20-CH measurements are supported by standard terminal, and 200-CH measurements are supported by extension terminal base
When using Graphtec’s GS series and terminal / adapter, acceleration, AC current, CO2, and illuminance / ultraviolet measurements are also possible
Because that standard terminal have a whole CH isolated, different standard signals can be measured at same time

Display & Operation

With high-resolution 7-inch TFT color liquid crystal display, confirm waveforms of measured data and each channel’s settings at a glance
Easy operation is achieved through straightforward menu structure and key allocation which resembles mobile phones

Data Capture
High-capacity measurement data can be saved directly in internal memory or SD memory card
Because SD memory card is used as an external memory, you can measure a long period of time with peace of mind while data backup (when optional wireless LAN unit is installed, SD memory card cannot be inserted into SD CARD2 slot)
Because disk image can be used for internal memory, multiple data can be saved
Ring memory capture function maintains latest data even after capturing for long term (set how long you want to keep data)
For voltage, temperature and humidity measurements, data can be captured at sampling rates of up to 10 m/sec per channel by using fewer measuring channels (Temperature measurement can be done at sampling rates of 100 msec and higher)
Equipped with relay recording function, 2 GByte or more data can be saved by switching to other file without data missing (when capacity of one file reaches 2 GByte, file is switched)

Data Control & Processing

Application software provided lets you set conditions and monitor data on a PC
USB drive mode function enables internal memory and SD memory card to be recognized as external drive by the PC (connect GL840-M to PC and turn on GL840-M power while holding down [START] key)
WEB server function enables control and monitoring from remote location without using dedicated software
FTP client function enables backup of measurement data to FTP server
NTP client function enables synchronization of time with NTP server
When optional wireless LAN unit is installed, data capture can be performed remotely by controlling GL100-WL

Details

The Graphtec GL840M is a compact, lightweight, multi-CH, and multi-purpose data logger with a 7-inch color display. 20-CH measurements with the standard terminal, and 200-CH 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-M can save the high-capacity measurement data directly in the internal memory or SD memory card. 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 multi-purpose remote measurement is also possible.
