10 isolated channels, each with multifunction input.
Its compact size contains an isolated input system which ensures that signals are not corrupted by inputs to other channels, thus eliminating wiring concerns. The GL220s 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 0-1V 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.
Large easy-to-read 4.3-inch wide TFT color LCD.
Utilises a bright clear 4.3-inch wide TFT color LCD monitor (WQVGA: 480 x 272 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.
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.

*4: The above figures are approximate.
*5: The sampling rate is limited by the number of channels in use. (10ms: 1ch, 50ms: 5ch)
*6: Standard USB memory devices without high-end functions such as fingerprint recognition are required.
Hot-swappable USB memory sticks.
Also supports popular USB memory sticks for external storage. The GL220 saves measured data directly to USB memory sticks. USB memory sticks can be replaced during measurement without data loss.
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.
Easy operation and device setup.
Ergonomically designed and easy to operate, just like a mobile device. The input/output terminals and keybord layout are arranged so that it can be operated in hands-on mode even when recording data.
Parameters in the AMP settings menu can be easily changed whilst viewing the waveform.
Easy Application Software.
Easy connection to PC.
The GL220 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 GL220 can emulate an external USB drive for quick data transfer.
Up to 10 units can be connected to 1 PC. 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.
Substantial data replay screens.
Three screens such as the Y-T (waveform), digital and the X-Y graph for specified data are available to view measurements in replay mode. The maximum, minimum, average and peak-to-peak vales between cursors are indicated in 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.
Other features.
Can be used with 3 types of power source.
Chose from AC supply, DC supply or the optional battery pack which enables 6 hours*7 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.
*7: DC power drive cable and battery pack are optional extras. Measuring time by using the battery pack varies on the conditions.
Alarm output function.
Alarm signals can be output when alarm conditions occur. Four alarm output ports are fitted.*8
*8: The Logic/alarm cable, (B-513 option), is needed to connect the alarm output ports.
Calculation function.
Measured data can be compared with other channels in real-time. Four arithmetic functions can be selected. The calculation result is saved as measured data when the built-in memory or the USB memory stick is selected as the destination for the captured data.
