GRA002-GL820 20 multi-channel logger (up to 200ch)
Includes Software, 100 to 240 VAC Adapter and User Manual
Huge 2GB Flash Memory,
modular system allows expansion up to 200 channels
Modular system allows expansion up to 200 channels
The standard configuration has 20 analogue input channels. It can be expanded up to 200 channels by adding optional 20 channelextension terminal kits.
All channels are isolated, each with multifunction input
Isolated channels, each with multifunction input
It contains an isolated input system which ensures that signals are not corrupted by inputs to other channels, thus eliminating wiring concerns. The GL820s multi-type inputs are suitable for voltage, temperature, humidity, pulse, and logic signals, enabling combined measurements of different phenomena like temperature/humidity and voltage.
Maximum sampling rate of up to 10ms
Provides faster sampling rates for voltage measurements. Can achieve 10ms sampling interval when limiting the number of channels in use.

*2:
For humidity measurements, the 0-1 V range and scaling function are used to display results directly in Relative Humidity. Sampling rate limitations are same as those for voltage measurement.
External sampling function
Captured data can be synchronized with external timing signals when the external sampling rate function is used.*3
*3:
The Logic/alarm cable, (B-513 option), is needed to connect the alarm output ports. TOP
Huge built-in 2GB Flash memory
Built-in 2GB Flash Memory for reliable long term measurement
The 2GB Flash Memory enables secure long term data measurement without using an external storage device. Data is retained even when power is turned off because flash memory is used.

Standard USB memory devices without high-end functions such as fingerprint recognition are required.
Ring memory function
The most recent data is saved when internal memory or external memory is configured in ring memory mode. Captured data size in ring memory mode is limited to 1/3 of available memory.
Hot-swappable USB memory sticks
Also supports popular USB memory sticks for external storage. The GL820 saves measured data directly to USB memory sticks. USB memory sticks can be replaced during measurement without data loss. TOP
Large easy-to-read 5.7-inch wide TFT color LCD
Utilises a bright clear 5.7-inch wide TFT color LCD monitor (VGA: 640 x 480 dots). Makes it easy to read data in waveform or digital form and to check your measurement parameter settings. The background color of the screen can be set to black or white.
PC-friendly, supports USB memory stick, has USB and LAN ports
Supports USB memory devices
Captured data can be saved directly to USB memory sticks when these are chosen for external storage.
Easy connection to PC via USB or Ethernet
The GL820 can be controlled by a PC if connected by USB cable, allowing transfer of data to a PC in real-time. If you need to move large data files to your PC then the GL820 can emulate an external USB drive for quick data transfer.
The WEB & FTP server function, FTP client-server function and NTP client function are supported when the GL820 is connected to the LAN via the Ethernet port. TOP
Easy application software
Easy connection to PC
The GL820 can be controlled by a PC if connected by USB cable, allowing transfer of data to a PC in real-time.
If you need to move large data files to your PC then the GL820 can emulate an external USB drive for quick data transfer.
Up to 10 units or 500 channels can be connected to 1 PC through LAN or USB. Measurements can be performed simultaneously or independently.
Various measurement screens
Select from 4 screens such as the Y-T (waveform + digital), Y-T (large waveform), digital view and report view to display measurements in real time.
The direct-Excel function enables captured data to be written directly to an Excel file.
Informative data replay screens
Three screens are available to view measurements in replay mode. The Y-T (waveform) display, the digital display and the X-Y graph can be selected to show your specified data. The maximum, minimum, average and peak-to-peak values between cursors are shown when using the digital display screen.
Simple configuration screens
The number of configuration screens has been reduced to five. Parameters can be set easily while viewing measured waveforms.
Useful functions
Post-process your captured data with useful functions for arithmetic calculation, statistical calculation, search and file format conversion.
The configuration of CSV file can be specified.
Alarm signals can be output when alarm conditions occur. Four alarm output ports are fitted.*7
*7:
The Logic/alarm cable, (B-513 option), is needed to connect the alarm output ports.
Alarm warnings can be sent via E-mail when computer is connected to LAN.
Can be used with 3 types of power source
Chose from AC supply, DC supply or the optional battery pack which enables 6 hours*8 of continuous measurement. The power source is automatically switched to the battery pack when the AC power supply is interupted. If the capacity of the battery pack goes low then measurement is automatically terminated and the captured data file is closed and protected.
*8:
DC power drive cable and battery pack are optional extras. Measuring time by using the battery pack varies on the conditions.
