OVERVIEW
Main unit only. Attached Connection Cable: Not covered by warranty

Hioki compact 1 or 2-channel data loggers feature a 60,000 data set/channel memory to measure temperature, humidity, voltage or instrumentation signals. The LR5031 logs instrumentation signals such as 4-20mA signals over 1 channel in as fast as 1 second intervals.

Key Features

• 4 - 20 mA DC measurement only
• Easily mount the light-weight , pocket-sized loggers in tight spaces
• Easy-to-see dual display
• Transfer data to PC even during recording*
• Replace batteries while recording (30 second limit)
• 3 times the memory capacity than predecessor (Record 60,000 data per channel)
• Measurement data is preserved even after the battery dies
• Worry-free backup preserves recorded data even if a new measurement is started by mistake

*Optional accessory is required and sold separately.

Note: Communication Adapter LR5091 or Data Collector LR5092-20 is necessary to transfer data from a LR5000 series Logger to a PC
