The Graphtec GL260 and GL860 are highly versatile, standalone data acquisition systems engineered for simultaneous voltage, temperature, humidity, logic, and pulse logging. Designed with fully isolated multi-function inputs, this series prevents signal distortion and catastrophic ground loops across all connected circuits. The ultra-compact GL260 provides a dedicated 10-channel architecture for tight spaces, while the mid-sized GL860 acts as a highly scalable powerhouse, launching with 20 base channels and expanding extensively up to a 200-channel configuration. Both models leverage enhanced internal flash memory, vibrant colour TFT displays, and comprehensive network interfaces to ensure continuous, unattended monitoring in demanding industrial environments.
Graphtec’s customisable input system and specialised memory handling sets these loggers apart from their competition. While the compact GL260 excels at rapid standalone 10-channel deployment down to a fast 10 ms sampling speed, the GL860 accommodates up to ten daisy-chained 20-channel or 30-channel extension units, enabling users to distribute contact blocks physically closer to remote sensors and drastically minimise thermal noise from long cable runs. Additionally, both units feature a unique Memory Loop function that automatically overwrites the oldest blocks of data once capacity is reached, preventing logging dropouts during long-term field validation studies.
The GL260 Midi Logger is an ultra-compact, 10-channel isolated data logger designed for precision field testing. Featuring a bright 4.3-inch colour display and 8 GB of internal flash memory, it effortlessly captures voltage, temperature, and humidity signals down to 10 ms intervals. Its standalone, lightweight design prevents ground loops, making it the ultimate grab-and-go solution for mobile troubleshooting.
The GL860 Midi Logger is a highly scalable, multi-channel data logger engineered for extensive industrial testing. The base unit allows for 20 isolated channels, but its modular mainframe expands seamlessly up to 200 channels to handle massive sensor arrays. Featuring a 7-inch widescreen display and fast 5 ms sampling, it is the ultimate powerhouse for high-density thermal profiling and complex field audits.
