4 Channel Data Logger GL980

High-speed 1MS/s Datalogger with Voltage and Temperature Measurements

GL980 is high-voltage isolated 8 channels data logger that supports 500V range, RMS measurement capability, all channel isolated simultaneously at 1MS/s and high-speed sampling. It can be used for machine performance and durability testing.
Inside, 4MW/ch internal RAM and 8GB internal flash memory. Outside, SD memory card and USB memory storage media. It is possible to record high-speed and long-time.
The DP-581H thermal printer can be connected and data can be handed over on the spot. It makes prevent data falsification and prevent data tampering.


Simultaneous Sampling with Isolated Inputs

GL980 is equipped with an isolated input mechanism to protect signals from interferences caused by noise from other channels. 16-bit A/D converter adopted to achieve hi-speed and hi-resolution measurement.

Simultaneous sampling

Simultaneous sampling

GL980 utilizes simultaneous sampling to eliminate slowdown in sampling rate by using multiple A/D converters in simultaneous sampling method.

External sampling

Sampling of the logger is performed in sync with an external device using an external signal input.

Multifunction input

Voltage, temperature, humidity, logic and pulse measurements can all be taken simultaneously in high speed.

Large Easy-to-read 7-inch LCD

Monitor data in multiple methods in addition to digital value display and full waveform display screen.
