HUMIDITY LOGGER LR5001

Record Temperature and Humidity Simultaneously with Dual-Channel Data Logger

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
  • Replace batteries while recording (30 second limit) (*1)
  • 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: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.
