HIOKI LR8450 Memory HiLogger: Modular Multi-Channel Recording, Up to 120 ch

Overview

The LR8450 is a modular multi-channel data logger. Direct-connect modules (voltage / temperature, high-speed voltage, strain, current, CAN, etc.) are purchased separately according to the measurement target, up to 4 modules and 120 ch. The LR8450-01 has built-in wireless LAN and can also connect wireless modules, for up to 330 ch in total; all other main unit specifications are the same.

Key Specifications

• Channels: Up to 4 direct-connect modules, 120 ch; the main unit also has 8 ch pulse / logic inputs (common ground, non-isolated).
