Overview of the Graphtec GL240 Midi Data Logger
The Graphtec GL240 Midi Logger reliably records up to 10 channels of voltage, temperature, pulse and logic data and an optional single humidity channel (with optional sensor). Sample rates are programmable from 10ms to 1 hour using an isolated input system that prevents signal corruption. This DAQ device accepts thermocouples and voltage inputs and can be battery-powered for portability. Features 4GB of internal storage and up to 32GB of external storage using an SD memory card. MicroDAQ, LLC is also one of the few Graphtec distributors that have an ISO-accredited calibration lab in-house to ensure your data logger’s accuracy.
