Data Logger | Humidity Logger LR5001

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) 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
