Introduction

The GRAPHTEC GL260 is a lightweight, standalone, multi-channel data logger capable of simultaneously performing multiple signal measurements and long-term data recording. It has approximately 8GB of built-in memory and supports SD card expansion, allowing measurement data to be stored in GBD or CSV format for easy subsequent analysis and management.

The GL260 features a fully isolated input design, capable of measuring thermocouples, voltages, pulses, and logic signals. It is suitable for a variety of applications, including equipment testing, process monitoring, environmental monitoring, temperature verification, and laboratory data recording.

Features

• 10-channel fully isolated analog input.
• Fastest sampling speed: 10ms (depending on the number of measurement channels).
• It has approximately 8GB of built-in storage and can be expanded with SD/SDHC cards.
• Supports CSV and GBD data formats.
• 4.3-inch TFT color LCD display.
• USB 2.0 communication interface, supports optional wireless LAN.
• Alarm function and Alarm History.
• Inter-CH Calculation.
• Memory Loop recording function.
• Supports multiple functions such as triggering, scaling, and data backup.

Supported Measurement Types

The GL260 supports a variety of sensors and input signals, including:

• Voltage (20mV～100V)
• Thermocouples (K, J, E, T, R, S, B, N, C, W)
• Humidity (requires B-530 sensor)
• Logic signals
• Pulse signal

High-Speed Data Recording

The GL260 allows you to adjust the fastest sampling speed based on the number of channels used:

Use Channels	Fastest Sampling Speed
1 channel	10 ms
2 channel	20 ms
5 channel	50 ms
10 channel	100 ms

Suitable for applications such as high-speed measurement, equipment testing and process monitoring.

Long-Term Data Storage

It has approximately 8GB of built-in memory, supports long-term continuous recording with an SD card, and supports:

• GBD format
• CSV format
• Ring (circular record)
• Relay (segmented recording)

It effectively reduces the risk of data loss during long-term testing and facilitates subsequent analysis and backup.
