The GL840 is the world's leading, comprehensive multi-channel data logger.
GL840 extends to two application-specific versions: The multi inputs model and withstand voltage model.

The Multi inputs model is suitable for temperature measurement with multiple channels and the Withstand Voltage Model is suitable for stacked high voltage battery application or high precision temperature measurement.

The GL840 has three types of input systems that allows different signals to be measured -

1. Multifunction analog input ports - The GL840 contains an independent input device that ensures that noise from other channels does not corrupt the signals. 20 analog input channels are in normal configuration. Optional 20 channel extension terminal base (B-566) and input terminal units can be expanded into 200 channels (B-564 or B-565). It offers a long cable for blocks linked directly to the terminal inputs (in the daisy chain) or by cable B-567 (s). An extensive communication cable can be used to stretch the input terminal unit and the GL840 main body.

2. Support digital sensors - The GL100 links directly to GL840 digital sensors and input terminal/adapters. For simultaneous interface, the dual-port Adaptor connects to two sensors.

3. 4 channels of Logic/Pulse inputs - It supports logic or pulse signal inputs for four channels. Cumulative, instant, or rotational values for industrial capacity measurement with speed and flow are given by pulse mode.

GL840 major features -

1. Built-in 4GB Flash memory with SD card support - With its integrated 4GB flash memory and SD card slots for external storage devices, the latest GL series provides accurate long-term measurements. The SD card slot is compatible with a 32-GB SDHC memory card. The recorded data can be stored in GBD or CSV file format (Graphtec binary data).

2. Displays the data by a bar chart - The integrated data calculated through the digital sensors can be seen in the GL840 series through a bar chart.

3. Alarm output function - The four-channel warning alarm ports can be mounted by alarm signals based on the set conditions.

4. USB drive mode - The role of USB drive mode allows data to be drag-and-drop to the PC from GL840.

5. Navigation function - Setting operation for measurements and wireless LAN adapter can be done easily using the navigation pad.

6. Large easy-to-read 7-inch wide color LCD - Waveform or digital format may display monitoring data. On the screen, you can show the parameter settings.

7. 3 Types of Power Source - Select the power from the AC, DC, or battery pack rechargeable. Further accessories are needed for B-514 or B-569.

8. Networking features - The network offers a variety of functions. Role Web & FTP server, FTP client, NTP client.

9. Cover (B-578) - Protect the body from esthetic disruption and minor effects. The cover is not intended to protect against harsh effects

Software - The GL840 has high-quality measuring and output applications with useful PC and smart device environment functions. It supports up to 1000 channels as a maximum. With direct Excel, the recorded data can be written into an excellent file straight away. You can set visually and intuitively the data recording schedule. A computer connected with the PC can be easily found and the process can be started. It collects GL main body data and displays digital value information in real-time, replays the data stored by the waveform in the GL body.

Wireless measurement using wireless LAN -
Wireless LAN allows wireless communication with any device. As a remote sensor, GL100-WL is now connectable to the GL840 with WLAN. The calculated data can be monitored and managed using the application software via a PC or an intelligent computer. The GL840 can be monitored remotely via the Internet by a router supported by a dynamic DNS service. In other words, wherever you are, you can contact your GL840.

The multi-channel data logger GL840 Graphtec embraces voltage, temperature, moisture, pulses, logical signals, and more. Some of the Industries benefiting from GL840 data logging are:-

1. Greenhouse and hydroponic agriculture
2. Building and engineering
3. Manufacture of machinery
4. Aerospace / Gas and Electrical automotive industry
5. Electrical and office appliances
6. Processing of foods
