The Graphtec midiLOGGER GL980 and GL2000 are premium, standalone data acquisition systems designed to capture high-speed electrical transients and precision environmental data simultaneously. Engineered with independent Analogue-to-Digital (A/D) converters per channel, these loggers achieve synchronous sampling speeds up to 1 MS/s (1 µs sampling interval), filling the crucial testing gap between standard slow-speed data loggers and high-complexity oscilloscopes. Both instruments feature a large, high-resolution 7-inch colour display, heavy-duty channel isolation, and extensive internal memory architectures to ensure rugged, standalone reliability in volatile electrical environments.
What sets this series apart is its tailored optimisation for high-speed voltage capturing without sacrificing traditional logger features like multi-point thermocouple logging. Unlike competing instruments that share a single A/D converter across multiple channels (causing a speed drop as you add inputs), the GL980 and GL2000 maintain their blistering 1 MS/s performance on every single channel, even during simultaneous multi-signal capturing.
Note: Sampling intervals faster than 1 millisecond (500 µs down to 1 µs) cannot be written directly to internal flash memory or external USB drives due to storage medium write-speed limitations. For high-speed capturing, data must first be written directly to the ultra-fast internal RAM buffer and subsequently saved or transferred to permanent storage.
The Graphtec GL980 is a high-speed, 8-channel isolated data logger designed for dynamic multi-signal testing. Achieving simultaneous sampling speeds up to 1 MS/s with dedicated A/D converters on every channel, it captures fast voltage transients and temperature profiles seamlessly. Its dual-input configuration (BNC and screw terminals) makes it the ultimate versatile tool for demanding electronic and automotive R&D.
The Graphtec GL2000 is a rugged, 4-channel high-voltage data logger engineered for safe CAT III 600V power-line testing. Capable of direct inputs up to 1000 V DC and 1000 Vrms, it eliminates the need for expensive differential probes. Featuring 1 MS/s simultaneous sampling and built-in True RMS calculation, it is the ideal safety solution for heavy industrial power grids.
