תיאור
The HIOKI LR8431-20 is a highly compact and portable data logger designed to provide precision multi-channel logging for voltage, temperature, and pulse signals. Featuring 10 isolated analog channels and 4 channels for pulse/rotation, it is the perfect solution for on-site diagnostics, long-term monitoring, or development testing across various industries.
Engineered for high accuracy and fast response, the LR8431 supports direct voltage input from 100 mV to 60 VDC and captures fast-changing signals with a minimum sampling interval of 10 ms. With 5 µV resolution and 16-bit delta-sigma A/D conversion, the logger delivers highly precise results even in low-level signal applications.
Designed for flexibility in the field or lab, the LR8431 can operate from AC power, DC input (10–16 VDC), or an optional battery pack (up to 2.5 hours runtime). Measurements are saved internally or to a connected USB drive with up to 16 GB capacity, enabling extended, unattended data collection.
Its robust noise reduction, including effective suppression of inverter switching noise and AC power line hum, ensures clean and reliable data — even in challenging environments.
