Three types of input system enable to measure various phenomena

Input system 1 : Multifunction analog input ports

Contains a highly isolated input system which ensures that signals are not corrupted by noise from other channels. The GL840's inputs are suitable for combined measurements from voltage, temperature, humidity, logic, and pulse signals.

* Accuracy rating for K-type thermocouple at 100˚C includes reference junction compensation. Accuracy varies by temperature levels and thermocouple types.

The following shows how a standard configuration is expanded to more than 40 channels 

GL840 is Graphtec's newest Multichannel Standalone Data Logger
