Hioki LR5001 HUMIDITY LOGGER

2-channel Temperature and Humidity Logger with -40°C to 85°C range

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.

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

•         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)

Note: 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.

•         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
