The Graphtec GL260 is a compact, standalone 10-channel data logger used for measuring various phenomena like voltage, temperature, humidity, pulse, and logic signals. It features an isolated input system for high accuracy and an 8 GB internal memory.
 

Key Specifications

According to Graphtec's website and product information from various retailers, the GL260 offers a variety of technical specifications: 

Input Channels: 10 analog input channels (all isolated, balanced input), plus 4 channels for logic or pulse inputs.

Measurement Types: Measures voltage (20 mV to 100 V), temperature (thermocouple types K, J, E, T, R, S, B, N, C), and with an optional sensor (B-530), humidity.

Sampling Interval: Programmable from 10 ms up to 1 hour (10 ms to 50 ms is for voltage only).

Memory: Features approximately 8 GB of built-in non-volatile memory and supports an SD card slot for up to 32 GB of external storage.

Display: A built-in 4.3-inch TFT color LCD display.

Alarm History Function: Allows easy viewing of the date and time history of alarm occurrences and cancellations.

Memory Loop Function: Enables continuous recording by automatically deleting the oldest files when memory capacity is reached.

Enhanced Calculation Function: Supports inter-channel calculations and the use of coefficients for specific analysis, such as temperature slope calculations.

G-REMOTE Services: A new service using a cloud server for remote control and data storage.

Software Compatibility: Comes with standard software (GL28-APS and GL-Connection) for settings, data recording, playback, and versatile data display on a PC.
