TEMPERATURE LOGGER LR5011

Main unit only. Sensors sold separately: 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 LR5011 logs temperature over 1 channel 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)
3 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

*Optional accessory is required and sold separately.
