HUMIDITY LOGGER LR5001

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 LR5001 logs temperature and humidity over 2 channels in as fast as 1 second intervals.

Key Features

Easily mount the light-weight, pocket-sized loggers in tight spaces
Easy-to-see dual display
Transfer data to PC even during recording(*1)
Replace batteries while recording (30 second limit) (*2)
7 times the memory capacity than predecessor (Record 60,000 data per channel)
Record without missing fluctuations in STAT mode
Measurement data is preserved even after the battery dies
Worry-free backup preserves recorded data even if a new measurement is started by mistake

*1:Optional accessory is required and sold separately.
*2:Recording is interrupted during battery replacement if the battery is very weak. After batteries are replaced, recording resumes automatically. Previously recorded data is not lost during battery replacement.

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