Record Instrumentation Signals and Measure Analog Output from Sensors and other Devices

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 LR504X series logs DC voltage over 1 channel in as fast as 1 second intervals, available in three different ranges.

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.
