Only the size of a A4 sheet of paper, the Hioki LR8400-20 series is the realization of Hioki's goal to build a logger that provides the existing functionality of a multi-channel data logger in a portable format. The new model comes with a 30 channel capability as standard, to which another 30 channels can be added. All input channels for measuring temperture, humidity, voltage and impedance are isolated for safety, culminating in a powerful multi-measurement system that also offers pulse and logic inputs. Long-term logging is coupled with the capability to protect data against unexpected power outages and othe problems for stable recordings over an entire year.
